As a long time eBay seller, I can assure you that there are alot of us out there that will bend over backwards to make sure a sale goes smoothly. As mentioned earlier, always look at the feedback of the seller, it says alot about that person/business. I also recommend looking at the feedback given by that seller. I've seen some strange/nasty things said about buyers that were uncalled for.
When I buy on eBay, another thing I always check is their shipping costs. I see so many sellers give their item a cheap price and then very high shipping. Sure, they get more hits on their items, but I don't consider it very honest. Just my 2 cents.
