Tell me I'm wrong but it seems to me that people get a little carried away bidding on the bay.
Example: I tried selling a superb Carlton frame on Retrobike for £75, an almost identical one went on the bay (last couple of days) for nearly £200!
If I'm looking for a particular item, frameset, whatever, I'll use a network of contacts to source them (or the less popular jumbles).
At fair - between friends/enthusiasts - prices.
