Listen, I have also had my share of 'experiences' with ebay and paypal, and they will in my experience 98% of the time side with the buyer in all disputes. For example, I sold an old Penn electric downrigger a couple years ago for $200 or so, stated that it was old and sold as is but tested to raise and lower (it did), shipped for a fortune because it was huge and heavy, buyer received, then weeks later complained that it worked, but a minor feature that tripped the switch off when fully retracted didn't work, so he had to flip the switch on and off manually. Buyer complained, I pleaded my case, paypal allowed buyer to return and then graciously refunded their payment including the original shipping which was about $60.
Bright side is I immediately relisted it, detailing the issue encountered in the first sale, and it sold for about 50% more the second time....

I also had them freeze my paypal account to the tune of $700 once when I sold a PS2 when they first came out. That was fun..... and unfair to me.
I guess what I am trying to say is that nobody puts a gun to your head and makes you sell on ebay. The experience is definitely not as good as it used to be, but if you think about the national, or even international exposure your little auction gets, and the fact that you are basically guaranteed a sale for the most part, I still think it's a fair deal. I've been buying and selling since October 1999 so I've been around the block with them a few times by now.
