> On the other hand, if you use that criteria you exclude basically everyone who is not a commercial seller, which is one of the main points of craigslist-type sites.
I was merely exaggerating criteria to get across a point regarding a very critical fundamental difference between eBay vs. Craigslist, not trying to list a comprehensive set of criteria for choosing reputable sellers. Evidently this wasn't clear, so to clarify: I also think someone who's merely sold 10-15 items of comparable prices over the past 4-5 years ago can also be sufficiently trustworthy if their reviews are 100% positive. And again, none of this is to say these criteria could not be relaxed or tightened depending on the situation, item price, etc... and, in general, you should also incorporate your common sense (which I would hope could go without saying).
