There may be frames and/or bikes that say Pogliaghi on them showing up on ebay on the fairly routine basis...but the number of those bikes and frames that are the totally cool 60s or early 70s items in anything like clean original condition is extremely low. Especially in the desireable 55-57 cm c-t range (which happens to be my size ;>). I can count on the fingers of one hand Pogliaghis of that sort which have shown up on ebay in the last, oh, say 4 years? I bid on every one, and won two of them, one of which I gave up to another CR list member.
So. The really cool ones are not at all common.

PS: ah yes. Holding out for the right bike. Chuck's right. Hold out for the right bike. Unlike moi, who tends to buy in haste, and repent at leisure. Not lately, though.
