What is the difference between this one....Dual speed electro-mechanical for $54 and the less expensive Marpac 2 speed for about $46????

Looks like the only difference between the two is price. Two speed/dual speed are the same. On mine, one speed is faster/louder, and the other is slower/lower. I typically use the lower setting at night for sleep. I rarely use the higher setting for living room or common areas that are louder. Depends on what you plan to use this for, but I feel that even the single setting model ($44) should be enough. Hope this helps! Good luck...

I believe the toxic is a better over clocker but the DCU II has better temps and noise level. I bought the toxic myself. I say which ever you can get cheaper, they are both great performers.

This is a variable speed motor. I am very rough on the motor, and it's really taken a beating. I love it! I recommend getting the MinnKota 60 amp breaker as well to protect the motor.

I have this air gun, it is ok....one of my compressors only puts out 135psi at 60cfm, this gun doesn't have the power the Aircat has, so recently have purchased the AirCat. The Aircat has higher torque and is a better gun....esp when we hook it up to a compressor that puts out 175psi. Hands down, choose the Aircat.

Similar. Bit more plastic in the 140 (I think the cooling fan on the 130 might not be plastic, but haven't used one in a while). The 140 seems to run a little better, 140 also has ability to run a spool gun that the 130 could not. I'd call it better, and the Millermatic 130 hasn't been made for a few years - if you can pick up a used one cheap go for it, but for a good 110V Mig welder this one is hard to beat. Overall they are very similar, intended for the same use. The 140 w/ Autoset just cranks a little more, and can be easier to use for "first timers". Mine, I recently was welding 6" SCH 40 pipe (capping it with 3/16" plate, for ornamental work) and I was surprised at how well it ran with .030 wire. It's a good machine, and great for the home hobbyist.

Unless you are buying this for yourself I would buy. It has plastic gears which wear out quickly in the running gear. I hear this common with most all of the lower priced RC's I does run about 15 mph which is fast. They make faster ones.

I don't think there is a technical difference, but this does have a very strong motor, I rarely use it on a high setting. Also This a an amazing product, not an amazing product for the price, but a plain amazing product! The price is just icing on the cake.

I'm very happy with mine. No, I haven't need two speeds. This one does what I needed it to do.

It is a case of personal preference, I think. The difference to us is that the Lectro has a more of a true fan sound which is a base sound while the Marpac is a higher pitch tenor. We have a two storey home and use the Marpac in the upper hallway between the bedrooms to mask sound from the stairway and movement downstairs while someone is sleeping. The Lectro is used in our bedroom as a "white noise" machine and is the one we pack into our suitcase for trips. MAC

This is a type of speed rating given to the ram as they develope newer models. judging by the types given here there isn't enough difference to call. you would be talking millions of a second now you could spend more money on the newer types but for every day use in home or business you would not see any difference. Now if you are trying to devolop some type of robotic instrument then the more power the better.

The 220 has Two max speeds (400 & 1400 rpm) while the 120 has One max speed (650 rpm.) Also, torque is 310 vs 115 inch/lbs. The B&D; site really sucks, http://www.blackanddecker.com/allproducts/20-volt-drills.aspx

Hi, not sure what the difference is exactly, but I must admit that I find this one much better than the previous one. It is lighter and more durable so I fully recommend getting 83 slow. Sorry I can't be more of help

I have never used the HF Mini Mill, but if it is truly a 2-speed unit, the Grizzly mill is preferable if only because it has a variable-speed motor.

There now seem to be at least two different-looking versions of this tool with the same model number available online (both Amazon and elsewhere) and ranging in price from $50 to over $100. For example the video on the Amazon page does the demo with a different tool (about $50) than the one shown above for $100. Which version is the newest most "upgraded" version, and which ones have been sitting in a warehouse? For $100 and claimed to be "upgraded" and engraved, I expect an accurate one first try, no returns or return postage or delays - or I might as well just buy the plastic version.

Quick answer is Motor SIZE. Looks like you are comparing the brushless motor version with the brushed motor version. The brushless is 380, the brushed is 550 titan. Brushless is faster, more reliable, longer lasting, etc, hence, why it costs more. Not only will the motor sizes be different, but the "motor mounts" and the electronic speed controller "ESC" included will be as well. I bought the 550 brushed version, you will be pleased w/ it. If you take this hobby seriously, when the motor dies just buy a 550 sized brushless motor AND ESC. Happy hunting

I wouldn't suggest u to get this one brandon. Spend the extra money and get a liquid cooled 4stroke . It is about 150 more but totally worth it have no complaints. I bought the cheap two stroke first and it is total garbage . Seriously do not waste your time with thetwo strokes.

With e-bikes 36 volts is better than 24 volts by far. So it stands to reason that 36 volts is way better than 20. I have the full collection of Dewalt 20 and 36 volt tools. The 36 volt tools do everything better if you need better torque, Higher RPMs or even much longer battery life and faster charging ! Keep in mind every 36 volt battery they give you is worth as much in time and power as 2 BIG 20 volt battery. Getting 2 x 36 volt batteries is as if they gave you 5 20 volt batteries. They also charge twice as fast and they allow you to drive into concrete, steel, stone much better than 20 volt systems. The circular saw at 36 volts will cut thru 4x 4 and 4x6 stock like it was butter ! The 20 volt saw is whinning and sputtering a lot. If you were going to get extra batteries with your 20 volt system, that cost alone will run your package beyond the cost of the 36 volt kit with 2 batteries. Thanks all
