Check the bike shops in Burlington, VT, there are several.
Earls is probably the largest- they usually stock Trek 520.
Old Spokes Home [OSH] usually has Surly CrossCheck and LHT in stock.
I've purchased bikes from both places. Earls, being a large store, is less personal with more sales pressure- they clearly want to move inventory. Their shop is fine. OSH is much more commuter orientated, friendly and do a great job. I would call either to make sure they have your size in stock and visit mid-week on a rainy day.
Plus there are a couple other shops in the area- no direct experience with them.
