I furnished almost my whole house through ebay and have intermittently sold, I'd just suggest that you can easily build up your feedback by buying some inexpensive things, and by selling items like books, cds, and other inexpensive goods.
Try not to be too wordy in your auction, I especially hate the ones that are a hundred lines of 'rules', I never bid on anything that is sold that way. Just ask yourself if you were buying the item what you would want to know about it, you can put a small disclaimer at the end saying how many days till payment is expected if insurance is available etc.
I love PayPal, it has saved me money by giving me refunds when a seller has been a loser. In fact I try not to buy anything on ebay without using PayPal.
I once saw a DVD on eBay that I wanted, but one of the sellers rules was that you had to ask for his permission before you bid. If you didn't, he would cancel your bid. So, I emailed him for his permission, and then promptly forgot about the auction. I didnt check my email for a few days. If I had, I would have noticed that he emailed back his permission. His auction closed without a single bidder. The problem wasnt that the DVD wouldnt have sold (it was a popular item usually went for 15-20 dollars on ebay at the time), the problem was that sellers dumb rule. I eventually bought that DVD...from a local store instead of online.
