Aha!! Old Fool (hardly..) is in the know! That is a helpful comment. Everyone always warns that the hp ratings are deceptive and all over the board. That being the case, how do you guys feel about choosing between the Schulz 7.5 hp (really then 3.5hp) 80 gallon vs. the Quincy 5hp 60 gallon compressor. They come in at the same price right around 1400 dollars. Is there some other model that I need to include in this short list? Thanks for all advice and comments. I find this to be a big sum of money to spend before even getting started on my project. That said, I would hate to spend it to find out later that I cannot run a sandblast cabinet and that I now own a 400 pound boat anchor.
