for your price range, your not gonna get something quiet. just go to sears and buy a 6hp 33 gal for like $300 with some air tools. it will do everything you need it to, but will be obnoxiously loud. i should know, i have one. home depot usually has better tool packages with their compressors than sears does though, for the same price
