i feel your pain... but i would never buy on ebay with a money order...
the only way, is to use paypal, BUT pay with your CC that is backed on your paypal account... leave zero$ ballance in your paypal and pay using paypal. So if anything goes wrong you can get 100% refund from your cc company. Ebay/PayPal will only give you up to 175.00 refund if you get ripped off.
i have been an ebay member since 97 (521 feedback) and got burned for the first time last month.... ebay could careless, but paypal has been helpful in trying to get our money back.
