Ron, buy as big of an air compressor as you can stand. I have a 7.5 hp Ingersoll-Rand with an 80 gallon vertical tank. It was about $1700 but after using up a couple $400 air compressors running DA sanders, air buffer/polishers, etc. the new one doesn't work hard at all. It mostly depends on your use.
