It'll come, I know. My luck with CL is that I usually find stuff when I am ready.
Working on a bent and within 3 weeks I found 2 excellent donor bikes for $50 a piece.
Been giving some thought to making my Schwinn Le Tour a single speed. Sure enough a 27" single speed wheel set shows up on CL, and 2 days later a crankset and new tires.
I'll probably troll ebay for a frame. I have a NOS SA hub and it would be fun to build it up from scratch.
