Hello, I just got hold of a Grundig YB 500 in new condition (I think it was a Christmas gift that was never used). Since I still haven't opened the box, I am considering auctioning it off on Ebay. How much would one of these be worth new with all the accessories? Also, if I use gloves in the process of doing so, would a quick test evaluating the functionality decrease or raise the worth of the radio?
