There's a typo in your link (an extra 7). Believe this is the one you're referring to:

De Rosa 1983 Team Sammontana Columbus SL Campagnolo Super Record Vintage Eroica | eBay

The price of that one is, I believe, knocked out of whack by all of the custom pantographed components. But it's still being put up there for at least twice what I think the market price should be.
