Marc;
You have the right attitude... I don't purchase too much from ebay, probably 4 items in the last 3 years and my feedback is zero. I consider myself an honorable person, being blocked from bidding would probably sour me.

3 of the 4 purchases were great. However, one purchase, 3 CD's my son wanted to our dismay turned out to be burned CD copies, even though it was not advertised as such. I had sent a check in advance before recieving the burned CD's.
