Need a new air compressor

Quincy is the way to go. Ingersol rand used to be good but they went cheap and only the high end ones are good quality. Here is the quincy I bought a few years back. I dont regret it one bit. It will keep up with sandblasting all day long and run any air tools with no problems. Two DA sanders at once...no problem.
Just make sure you have sufficient electric to run it. If not, step down to the 5 hp model.
