I agree 100% with Mark. And it is 120 degrees OR 95% OR both here most of the year. He's not joking there.

I have no problem with the fan noise, I have a lot louder things I live with. The compressor charging when I am on the phone bugs me some, someone grinding when I'm on the phone does too. But that's sometimes how a shop works, at least for me.

I would rather not have on-demand and get a better duty cycle and know I will get (if I keep it clean and covered ) a lot more time/use out of my machine.
