Be careful when going to Trophy Bikes around any holidays. They say they're open everyday, but when I was up in the area over Christmas, both of their stores were closed for about 2 weeks. There was no notice on the website and it wasn't mentioned on their phone message. Fortunately the Downtube store in nearby Bensalem was open.
If you're ever in Florida, Orange Cycle in Orlando (Dahon) and Revolution Bikes in St. Petersburg (Dahon, Bike Friday, Giant) keep some folders in stock.
