The ESP Guitar Company

I don't know an exact figure, but if it's in really good shape it could fetch around $2k in the US. The gear market has been kind of flaky lately, though. If it's a really desirable model, it might be easy to get top dollar, but if it's not, you might not be able to even get a fair price for it.

You might get a better idea from a forum where people are more hip to the vintage market, like The Gear Page.

If you are up at that price with bidding already, then that is probably a good sign that the market for them is still happening. People will always try to go for a steal when it's an auction, so figure you might reasonably get more if you were willing to hold out for the right buyer. But then again, that's kind of what I was saying about the market right now: A few months ago, you could practically flip any 'hot item' amp with little to no loss, but people seem to be a little hesitant to pay the big money right now except for a few really desirable pieces, like Cameron modded Marshalls.
