I'm going back to bargain with them tomorrow; will let you know how it goes.
I was actually hitting the pawn shops (evidently, there's a merger going on and prices have been cut drastically on old inventory) looking for a upgrade to my beatup Motebecane. They had a gorgeous Rockhopper 29er, excellent shape, reduced to $50. Sadly, it was a 23" frame. I may grab that as well and flip it, though.
