Well, they've been sold for a little over GBP90 (say 180 US Dollars). At 45 quid each that makes the possible price of brand new ones seem a little more reasonable!
Odd thing is, the same vendor has a WP camera, a Conley with non-original spring back, which has so far only attracted one bid at GBP9.99 and hasn't reached its reserve price. I gues all the WP fans out there already have their cameras but lack film holders?
Even so, at 45 quid a pop I think I'll stick to 10x8. It's cheaper....
