Hello, I hope this isn't the wrong place to post this. I am planning on selling my Polk Audio RT7's. According to Polk's site they retailed for $223 each. They are in good shape as far as I know, although some of the black finish have come off. A friend of my girlfriend is interested in them, but I have no idea what a fair price would be. Could someone give me a clue? If it ends up being a lot more than what this guy wants to pay, I will probably post them for sale here, or eBay. Any help would be greatly appreciated. Thanks!
