Since we are talking about people and stones, i used to purchase some parts off ebay, from swapmeet. there was no problem as long as there was no problem. I would pay and he would send parts. but once he sent me parts that were damaged and rusty, his response was (thats the way they are) i wanted to return them, he would not reply to my messages. I got his number and called him, he brushed me off. He was a real$ %#^$*. I did get my money back from paypal. I will not buy anything from him again. Jeff
