eBay is about the best....just don't think that for one second you are protected, that's all. If you are selling high dollar stuff $1,000+...you need to be careful...if you are paying them 10%, then they are going to allow the buyer to use your item, then return it with just a "item not as described" comment, you will be out your 10%, the buyer will have used the item, they(eBay) will expect you to provide the shipping from the buyer back to you, and now, if your lucky, you'll get back what you sold... maybe not....
I've heard that Amazon is even worse...
I'm confident a lot of buyers are aware of this, and using it to their advantage
