I have a 218V BEL-AIRE, and couldn't be happier with it. It is a little louder than all cast metal compressor pumps as it uses 3 piece pump with an aluminum block and cast iron upper piston section and aluminum head, but it is an all USA made unit using true high quality pieces. And they can be found for reasoneable money. I bought mine last year for under $1200 after tax. A friend of mine uses the 318V and runs a body shop and has no complaints about his, and is why I chose one. The QUINCY units are also nice, but you do pay a premium for the extra build quality. And I would avoid the ingersol rand units as all the research I did showed they switched to cheap made in mexico electric motors about 4 years ago that are failing in the first 2 years at an alarming rate.
I know I did ALOT of looking and research before I decided on the BEL-AIRE, and the turning point for me was they seemed to be one of the only made in USA ones out there for the same money as the imports. For your demands I would say the 318V would do nicely.
