considering I had this guitar made for me and I oversaw its setup with two luthiers and I originally spent the dough for it, I have a very good indication of what its "worth".
One offs like this guitar, just like stated previously, are not high resale items at all UNLESS the other party puts the same or higher value than yourself on it. I had this guitar in the making for almost 2 years...by the time it was done I was pretty lackadaisical about it so I rid myself of it. It is a spectacular guitar and I won't deny I miss it from time to time...but in short, it wasn't my thing anymore. Unfortunately, that is the way G.A.S. will play itself out to you....don't rely on what others think its worth..concentrate on finding someone who values it as much as YOU do and then you'll get a just trade or sale...so patience is key.
Congrats on your new guitar..(damn this guitar keeps getting traded around!!!)
