Ellery,
GC generally likes to move their overpriced prestiege pieces after they collect dust for a few years...before I found the S2 I'm in the process of buying, I contacted them about Series basses. One, which may have been this one, had sat around for something like six years tagged at $4K. No surprise there. But after I got them to check the Blue Book value (duh!), they agreed to sell it for $2.5K, and that was without haggling on my part or them smelling cash/credit card/my firstborn.
Point is, there's a decent chance they'd go below the $2600 minimum bid if it doesn't sell, which I predict it won't, unless one of us obsessive types gives in and rescues it. Forego the upgrade for a while, and it could ease the pain of investment a bit.
Just my .02, or .03 in your country (grin).
