Well this isn't a Heuer, so Heuer experts probably wouldn't know much
There is a TAG forum, a sister site to this one - forums.calibre11.com - where you might be able to get better in-depth information and knowledgeable opinions, I think a bunch of the guys over there have these (or have had them in the past)
However - these practically grow on trees and are available in much better condition for the price you've been quoted, so I'd continue searching. eBay, WatchRecon, etc - there are a couple a week usually.
