Had a bad buying experience on this forum, seller name is 'weemuscles'. Paid for an F3 screen which never turned up, communication was terrible and no refund despite the seller saying he'd refunded some of the money (he gave a bogus paypal I.D.). He claimed he'd posted the screen 3 times, no calling cards from royal mail were ever left and no evidence of postage ever supplied. Funnily enough a quick look at his ebay feedback reads that 'postage not collected, returned 3 times' for another buyer of other items, so I'm not the first person to have had this treatment. He also asked for the paypal payment as a gift, so no comeback on him. Avoid.
