i know the mechanics at trophy and therapy, and have seen bad work come out of both shops, which happens at every shop occasionally. some of the mechanics at therapy used to work at trophy anyways, luckily its the raging alcoholic that left trophy. i would never let that guy work on a bike.
as for expense, yea trophy's got some pretty high end bikes on display (if, waterford, etc), but they also have reasonably priced bikes/merch too. besides looking at that IF lets me dream about mine someday. when you walk into therapy all there is is a sea of litespeed (not my thing)
so, i guess my favorite shop in philly is trophy.
