I got that same compressor - been using it on my truck and to paint various motorcycle bits. I have used it with hi torque impact wrenches, hand grinders, needle scalers, air hammers, air nibblers, HVLP paint guns (the whole truck - many bikes), airing up big tires, and even a HF sandblaster - but the sand blaster uses just a big hose and a ball valve to make it go. The sand blaster is the only thing that made me have to stop occasionally to let the compressor catch up.
Its marked extreme duty, has a 3 year warranty, and has a big cast iron 2 piston pump on it. I change the oil once a year and when I use it, it's used a lot, and when it sits, it sits for weeks.
Mine has worked very well and I paid that same 389 for it 2 years ago. I can't complain and I have had very good service from mine.
Now, mebe some of their other products weren't so good, but mine was/is. Mebe it breaks tomorrow, but so far so good.
