Selling has become a different animal on ebay now.. they've leaned drasticaly in favour of the buyer due to the feedback policy changes.
If you know how much the value is on something i'd just create a list and pop it round all the forums online, keep it updated every 3-4 days by bumping it, eventually you'll sell it off, ebay will give you alot of coverage but it will also take a good chunk of your profits for it, you have seller fees % fees, listing/insertion fees and finally paypal fees to come out of your final sale price.
If you sell it without ebays help, your gonna have most of the profit to yourself.
I'm not sure how ebay works on the US site but usually the insertion fee is depedant on the listing value. I i listed something for say £1.99 the insertion fee might be 15pence. Where as I listed something for £14.99 the insertion fee might be more like £1.19.
My advice would be to cut out ebay alltogether and sell it to a base you already know, if its a product your familiar with and know the value, get the true value for it by private sale and pocket the profit.
