Since the Sigma line has not been in production for several years, the guitar is probably used and I would want to know why the previous owner got rid of it--just like with a used car. I have a friend who deals in Cort guitars and they are very well made and sound great. Depending on your budget and availability, you might see if you can do some A/B comparisons with a Yamaha FG720S-12 or a Yamaha LL16-12. Also try the LAG line of guitars, along with Bedell/Great Divide guitars if you have not done so already.
