Paint set up recommendations?

Jim Kueneman said

Also recommend an air dryer too. I fought the first 2 paint jobs with descent snakes and water fish eyes. Bought the dryer and wish I had it years ago for sandblasting and my air tools.

Agreed. Here is what I have. It costs less than $100. It has a paper cartridge that looks kind of like a roll of toilet paper. It works really well. I would buy a few extra cartridges, because in humid weather they need to be changed. Just take out the damp one, put a dry one in and let the damp one dry out.
