I have heard good things about Devilbiss on the internet, I have a friend that has a Devilbiss dryers on his paint booth. I just recently purchased a Devilbiss QC3 130525 off Amazon. It has 4 1/2 stars out of 5 on 61 reviews, so pretty good reviews based on that many reviews. I also purchased a Ingersoll Rand F35341-400-VS Air Filter that I am mounting before the dryer to take some water out before it enters the dryer. It will allow the dryer to last a little longer.
Also just curious why you posted this in the Western Star forum? It doesn't relate to Western Star in any way.
