I have one of these, I have had a few Wolfgangs and currently have several. My STP is the best playing, best tone Wolfgang I have ever played, ever. If you are not a trem guy, you will love it. If you really want the D-tuna Floyd bridge, you may be disappointed.
I believe this guy is way overstating the value on this one. Last month, I saw an immaculate Sunburst with all the case candy, neck protector included, go for the BIN of $1000. I think he's asking too much, even by ebay standards. I check them out at ebay every now and again, looking for a bargain.
Also I would be very careful regarding wear and grime. these have been out of production for awhile now. Clean, lightly played examples do fetch a premium price, but wear and dirt quickly decrease their value. I would want better pictures of the frets, back of the neck, serial number and closeups of the chrome bridge and hardware. For that price it had better be perfect with all the tools and neck protector, original receipt too.
