I was looking for a stand-alone DVD player just recently, and in my search I discovered there are outfits that take certain DVD players, modify them to be "region free", and then sell them via the internet. I imagine they work ok, but you can surely kiss the mfg. warranty goodbye on these units (though that might not be a concern for some people). Just do a Yahoo or Google search for "region free DVD" and you'll find a lot of them.
