A goodly list Jason. I don't get to many of these roasters but I would certainly second the motion for:
Counter Culture Coffee, Durham, NC (Aficionado still my favorite)
Intelligentsia Coffee, Chicago, IL (Black cat - better again)
PT's Coffee, Topeka, KS ( a great Sidamo SO espresso)
I'd also add
Caffe Fresco, Port Griffith, PA (love their Ambrosia)
49th Parallel Coffee Roasters, Vancouver, BC (check out their Epic espresso)
Cheers
