AdmRose,
I've only ever had two problems with Ebay transactions.
The first was with a buyer who thought that the brand name of a teapot I was selling "Victoriaware" indicated that it was a Victorian teapot (even though I put "almost new - hardly ever used" in the ad and it sold for under $30) and when she received the teapot she posted snitty feedback saying essentially "This is not the like new condition 100 year old teapot I thought I scored for peanuts." I've often thought ebay needs to add "rolleyes" as a response option after that.
The second was a DVD player I bought in "non-working, as-is" condition in order to get parts for my own DVD player of the same brand. When I received it, the "DVD player" turned out to be "non-working" because it was just the case and the power supply. Well, yup, that's not gonna play a DVD, you betcha.
Aside from that, I've had a generally good experience with Ebay, in fact, much better than many other retail experiences.
