Try looking on SeatGuru on USAirways-Beechcraft. I disagree, but at least it is a start.

I've sat in most of the seats by now flying US4651-US4652 PIT-ART-PIT. My STRONG preference is 1A. Then 1B but watch out for the fire extinguisher and the closet. But if you can't handle the lack of a window, don't do row 1. Then any seat but the exit (4? 5?) in order front to rear. 9 middle is the WORST seat if there are people next to you. Probably OK if not, but I haven't sat there.
