trust High Desert Audio, but with EBAY dont belive anything anyone says, even if it sounds good. If its to good to be true than it IS, dont buy it. Read every part of the auction- EVERY PART. Make sure when you are looking for stuff you reaserch it and know what your buying. Buying from big websites (stores) on ebay is really no advantage over regular sellers, just know what your buying and dont buy anything without a picture. Never Inpulse buy on ebay- you WILL regret it.
I agree with davids but dont only look at the percent, look at the feedback from the last two months or so, is it stable at good feedback? Some sellers are so big they may have 98 percent but lots of negatives in the last month or so, look at what they have done recently and also have they sold the same thing you are buying? You can also ask recent buyers a question about the same thing you are buying, I do that quite often and find that most folks don't mind you asking......
