eBay and Craigslist finds

Yeah. Good price if you can pick it up.
Not sure the seller knows what he's talking about though, so the frame could be better than he's letting on. I like the seatclamp area, and it looks like there's a columbus sticker at the front yet he says alloy.
Nothing on it looks aluminium to me.

That caught my eye the other day. Looks like columbus air to me. rather rare and expensive (since it has the seatpost).
