In 1999, I bought one of these pancake compressors (1.5 "HP" and 4.2 CFM at 90 psi): I think it was $79 with a coupon... anyways, I once ran it for nearly 8 hours straight while porting a set of cast iron cylinder heads with an air die grinder (NEVER again!) and it never overheated or freaked out on me. Almost fifteen years later (in a couple months) it still works just fine. I have had three of the 2HP, 8 gallon air compressors they had a coupon available for in every flyer about 6-7 years ago... the first two went back under extended warranty and the third one has lasted about 6 years now. The pressure switch is the thing that failed both times on the first two... the diaphragm tears or something and they then just leak air and never turn off. I don't like how thin the steel is on the tanks (I have seen pics of entire garage walls blown off when a tank blows) but the motor and pump have never done me wrong. BTW, the 3/4 electric impact totally kicks A$$!!! The 1/2 drive one is good, too - - but the 3/4 (with a 3/4 to 1/2 impact adapter) is one of my most often used tools. I HATE air impact wrenches, they seem to most often convert air pressure to noise really well and not so great on taking off nuts and bolts.
