Query: OK regulator, wouldn't buy it from Amazon

This is an OK regulator, with drawbacks..... it doesn't come with a hose, which I knew, but should have given more thought to. Also, the tank attachment is not the new standard, so that had to be replaced. Again my falt, I should have been more diligent. But the biggest complaint I have, which I also should have caught, is that the shipping price from Ace was more than the regultor itself, making a less than $20 regulator almost $40. I expect more from Amazon.
