If you are selling gear and you have not had any bites here, I'd definitely recommend Amazon.
I've sold a good amount of stuff (books, camera gear, other electronics, etc.) on Amazon. Fees are pretty minimal and it's a definitely a place that creates a lot of traffic.
I had my 50mm 1.8 II listed for $85 + $4.99 shipping (Amazon has standard shipping prices depending on the product).
Keep in mind I listed this last night. Sold about an hour ago. I get just under $82 in return.
With current eBay/PayPal fees, Amazon is a good 'last resort.'
Lastly, if you are selling it for the lowest price in the MarketPlace, you're guaranteed to be the first hit when people are searching.
What do other people think about selling on Amazon over eBay?
