One reason that I have thought about only taking money orders is the Paypal system can allow someone to pay you, then claim they never recieved the item. Sometimes, when this happens, Paypal takes the money back from you before they even investigate.
I had this happen to a friend. He sold a bumper to a Mustang or something...guy paid via Paypal. Friend let him know it would be a bit before he got it shipped. Guy told Paypal that the seller wasn't sending him his item. My friend sent the item, then the next day Paypal debited a few hundred bucks out of his account to give back to the buyer because the item hadn't been sent. My friend contacted the buyer after he was sure the item had been delivered, and the buyer refused to send another payment...thus, my friend sold a bumper to a guy for no money...
