Thanks Alan...actaully I was also looking for whay the going rate would be if I choose to sell it (and if anyone out there is interested). As I said before in my post it is a Sigma DM-4S It was my dad's; unfortunately he died right after he got it so it is never played. It says Sigma Guitars Est. 1970 @ top & it was purchased @ 1997 or 1998. Thanks so much!!! Kat
