Acknowledging that you've forgotten more about this subject than I'll ever know, I own this compressor and I'm not sure it's as bad as you think.
I raced it against a Harbor Freight compressor rated at around the same CFM and found it to be about twice as fast at filling a tank. With a 1/8" sandblaster tip, this thing will hold 90psi forever. Maybe it is 14cfm, but as a practical matter, I can't find a way to outrun it.
I haven't had any problems with durablility, though that's not saying I wont. As I recall, if you use the IR startup kit, it has a pretty good warranty. Running it constant in nasty conditions for around 6 hours a day for a few weeks doesn't seem to bother it.
I know there is a lot of bias against Chinese stuff on this board, but I wouldn't say that a Made In America sticker assures quality any more than a Made In China sticker assures junk.
The point I was trying to make is that if you have a budget of $XX, be sure you balance the quality of all the parts of that system--electrical/compressor/dryer/etc. If you've got the dough, absolutely go Quincy.
No. Wait. Actually, my point was "for God's sake take it to a professional and pick it up done a week later!"
I'm still cleaning alum. oxide out of my ears and the **** got into my wallet and ruined all my credit cards. Oh, and it got into my shoes and ruined all my socks! Oh and...
