Anyone had good luck with posting on CL stating you'd like to buy an older bike looking for a good home? I'm looking for a 70-80s 64-66cm bike in Portland, OR to convert to a SS and it seems I'm late on the few good deals I've seen around my budget ($100) and those that are on there that fit my criteria are flippers with the price marked up too high since they're Vintage.

Thinking I need to be patient as I've read in other posts. Been looking for roughly two weeks so far. Local Goodwills have nothing at this time.
