I think Lazarus will go up in price, especially now when everyone knows there will be no more of them made. Most Bonamassa signature guitars now sell for substantially higher prices vs when they were released.Last time I looked, the "sold" listings seemed to all be in the $1k range, and chances are, a lot of them accepted offers below the asking price.
Now that it's apparently become official that no more Lazaruses are coming, there may be a bit of a bump, but I think the lemon burst 59s from Anderton's will prevent the Lazarus from going way up like some of the other Bonamassa runs did
