Awesomely handy. Thanks!
My one suggestion, would be to add a "view feedback" button to each. Often times, scam accounts will have 100%, because you're unable to leave anything but positive feedback that were in dispute. Happened to me a bunch of times recently, where selling an iPhone, and the user was just winning auctions, and not paying. You couldn't leave negative feedback for a nonpayment. It's insane!
