ebay has become big and successful because it works. Believe it.

On a personal note, I had great success selling games on ebay, using their dutch auction - a fixed price and multiple copies of the same item. I mention this, because in this manner ebay becomes your storefront - selling the product and collecting the cash, without bids but as a direct sale.

I know plenty of folks who have used ebay to buy and sell, for years. All have good stories to tell.
