You are kidding, right? You noticed the number of mcintosh components with their wood cases inside that audio rack, right?
I agree with the other posters above that, that is most likely is a very bad move, especially over the phone. Assuming it is not a scam but a genuine posting, then either that listing is accurate as stated or it is not. If that ad is indeed accurate as stated then the likelyhood of successfully closing any legitimate deal that is that far under the value of even "a very good deal" rapidly decreases with each tick of the clock. If you do happen to hear from the seller, don't negotiate or dilly & dally over $10, close the deal for the $200 asap, pdq, post haste, pronto, el quicko. rapido, das fasto, wham bamm, like yesterday dude!!!!
