Cort makes very fine guitars, my friend owns one, and it's very playable and have a MF sound. It's electric, viva series I believe, and it's very similar to Ibanez guitar I own, Ibanez S series. I don't know if it's a rumor or true, but I've heard that Cort was a sub-factory of Ibanez, just like Starfield was, but don't take my word for granted.
Anyways, if that guitar you're looking at and have second thoughts about buying because owner fucked up an instrument, at least try to lower the price. If it's buzzing that much, it's not worth $200.
