Best fix can be the cheapest way too.

Most tubeless values will last years. However, they are prone to gumming up from the tubeless solution and rather than buying a new valve, replacing the core is the cheapest way to get things right again. These work on Trek and Stan values, as well as others, I am sure.

As a new hobby I repair used audio gear from flea markets and thrift stores.  Most of this stuff is pretty easy to fix and the repair parts pretty cheap.  Surprisingly enough, one of the most expensive replacment parts are the padded feet. After 20+ years most of the units I work on have missing or rotted feet. Since I usually give the repaired items away, I want to keep my cost down.  They aren't ideal for some of the heavier amps, they do compress over time even stacking a few. But for the most part they keep the bottom of the unit from scratching the wood. If the end user wants to spend $20 or more on audio grade feet, good for them.

Easy do-it-yourself project that will save you a fortune.

Calling a service person to replace this part would have been prohibitively expensive.

Much cheaper than a new one, plus you can keep the working parts from your old unit to use for future repairs.

OK for a quick cheap fix. The locking mechanism is very cheap and didn't work properly. Had to cut it off and manufacture a homemade remedy.

A cheaper alternative to replacing the whole door.

This may be the best kept secret in the Refridgeration repair industry. Millons have been wasted on good Refriderators that could have been fixed for less than $12. If only Washington could work this well!

With free shipping- at $75 this is the cheapest place to find this part anywhere.
Came (in a huge box) on time, and was a perfect fit.  This is an easy car repair that anyone can do if they don't mind getting a little dirty.

I used this to temporarily fix a clutch cable on my motorcycle. Once the replacement I ordered arrives, I'll take the whole cable out and keep it for a spare for emergencies.  There are many choices for the ends.  Some seem like they are more likely to cut the cable then others so take a few minutes to look through them.  Their are two cables.  One is thin like you would get on a bicycle.  The other is thicker, though still not as thick as the cable on my Motorcycle.  However it is holding so far (2 days) and I is a good temporary fix until the replacement I ordered arrives.  It was easy to put on and would have been an easy fix even on the side of the road with a pliers and screwdriver.
You just slide out the old cable, slide this new cable in and attache the correct end.  Well worth the money for me.

The best strategy is usually the more simple one. This is easy to understand and easy to apply with a little effort.  And the price is only pennies of what it's worth is.

To start off, don't base your decision on these weights off of all the negative reviews you may read. I will state the simple problems and solutions to each one. I purchased 3 total sets, 50 pound set, 105 pound set, and 200 pound set which cost about $400 total. This is the cheapest and best option to obtaining the most weight as now I have over 360 pounds in total dead weight, 135 per arm, the reason for stating this is because this is absolutely the cheapest solution for the most weight. Now most of the complaints span to roughness of the handle to as ridiculous as giving one star for weight plates being to "greasy" upon first opening. The first major issue stated is that the star twist clamp doesn't stay tight enough for safe heavy lifting which causes the weight to constantly have to be checked for safety. The first obvious thing is that you should always check your weight for safety no matter if your clamp is tight or not, and I will assure you that if you tighten these clamps and put actual force into it they will stay put, take out the rubber rings if you must as that helps them stick together, for those of you that cannot put so much force than simply twist the last weight plate next to each clamp right and this will tighten it with little effort. The next most complained about is how rough the handle is, and metal splinters are common upon first opening, I will make it clear that I received 3 different sets of handles through my total orders so I know the extent of how rough they may come and honestly if your used to holding a shovel or have used lighter weights than you'll be fine, the metal splinter shards that people have stated really are not extreme enough to give these dumbbells one star over, this goes with the greasy weight statement, just have some paper towels like I did or a rag to be prepared to wipe down each weight and handle, I expected to do this even before my first order. When it comes to scraped paint and dents and scrapes in weight plates the scraped paint is minimal and expect to see some of the paint slightly come off when first using and especially upon opening, as for dents there is none, the "dents" are just how some come and is expected to see in every type of weight plate, I will show another picture for that. The last issue stated is shipping, know that the 50 pounds ships in 1 box, the 105 ships in 2, and the 200 ships in 3. Some have stated to be missing weights and handles which is really not to be expected so I wouldn't worry as I received over 7 packages in my 3 back to back orders and received every part of my order with no issues and received each order in only 3 days with free shipping. These weights are heavy duty and meant to last a lifetime and also not for beginner weight lifters, which is why there are so many negative reviews. These weights are perfect for if you need heavier weight and cannot afford it, do not expect pretty smooth handled easy grip amature weights as these are great for hardcore workouts and great to push you to your limits, and sky rocket your strength, if your truly for lifting than you will be completely satisfied with these weights. I have tried my best to accommodate every question as I wish I had this review when I made my major decision on this big purchase as major insight really eases the mind. I hoped this helped.
