mine was also a project.
I had some parts from another ss bike, which I sold part of. Some parts, like the wheelset and fork, I ordered through webcyclery. I got the frame on e-bay. The other parts, cantilever brakes w/ levers, cranks, chainring and guard, stem, and various other parts I had lying around.
I am considering riding flip-flop in case my freewheel goes out on a ride. I have a Surly rear hub, so I may go for it.
