LG BD 550 (w/o bd live) or LG BD 560 (with profile2 bd live)
AFAIK, most LG dvd/bd players can be made region free by going into their service menu and making them play "ALL" regions. How to get into the service menu - you will have to search on the net first. So check the net for the region free hacks first.
Just so you know, i dont have a LG bd player, just a dvd player which i made region free by going into the service menu.
