I mentioned Illy in my original post, when I started this thread. But I can't see paying $26 per pound for any coffee.
Illy is good stuff, but I don't think it is superior to any other typical espresso roast. Dark roasted coffee tends to taste pretty similar.
My everyday coffer is mail-ordered Torrefazione Settebello from Studio LX in IL, but that's bagged, not canned. $9/lb.
If you won't go $26/lb, then I'm guessing that Kopi Luwak is entirely out of the question?
