Site for purchasing unlocked phones

[jimswms]

I was just wondering if there was a legit site that people use to purchase unlocked phones? Mostly, I'm looking for a site that sells US based phones, so I know they'll work correctly on our networks, legit site for warranty, returns etc. Does this exist or is it just ebay?

Thanks
