These have been fetching 200-265 USD the past year or so. I'd be a little surprised of they ended up far outside that range.
In spite of the economy I'm not seeing prices on desirable vintage cycling stuff generally coming down on Ebay as one might expect. Lots of less desirable stuff with highish starting bids going unbid on, but the sought-after and rare stuff seems to be holding strong. At least the stuff I find interesting enough to follow has.
