I can't speak highly enough on Quincy compressors. My QT-5 with the extras has been a blessing to my ears. It's 3 years old now. I can stand next to it while running and talk to myself without raising my voice to hear. More importantly, I don't crap my pants when it kicks on, I can't hear it in the house (I could hear my old one from my living room with the TV on) and I will never need to buy another, unless I get into something that requires more than 20 CFM sustained. I cried a little when I paid for it, but I got over it the minute I got it hooked up to power.
Totally missed it, and added it to the editable poll!
