The compressor issues has been debated for a while. Just comparison shop. Anything 5 hp. or better and at least 60 gal. should do fine. I would go bigger and did with 80 gal. Spend a little more now and you won't be wishing you did down the road.
Use black metal piping out of the compressor with a loop/dip/ drop to help with condensation from the hot air. Then put a filterin place. I used the rapid air system after that and it works great. I can post a link to a pic or two if you want.
