Hi Mark:

The Haselblad glass-especially for the standard 80mm lens-has fallen in value pretty dramatically over the past few years. If you are really interested, go to that site and bid for a lens-just what you want to bid and can "afford to" pay. Don't budge, and be patient. There are a good many lenses for sale. You might be surprised to find something fall into your lap!

Best of luck.
