Firstly, this is a way off base question.

I want to sell my DSLR gear that isn't being used (Sony A850, two Sony flashes, memory cards, etc.) and I am wondering if there is a customs charge to ship items to the U.S. from the Caribbean (I checked the US Customs site, but that didn't help at all!), i.e. if I wanted to sell my gear on eBay (can you sell digital gear on APUG, or is that sacrilege?), would I be able to just ship the item to the purchaser, or would the purchaser need to pay customs in order to receive the item? If the purchaser has to pay customs, how easy of a process is it (it is a massive pain here!) and how much (percentage) is duty on digital camera gear?

Just assessing the feasibility so any help would be appreciated!
