Of the top of my head, the toshiba BDX1200, BDX3100 and BDX3200 can be made region free for DVD and multi region for blu-ray with help from a firmware update, but for the prices I've seen for them now you might be better off getting a blu-ray player from multi region magic which has been modified to be region free for DVD and multi region for blu-ray (like the firmware update toshibas, the BD region has to be selected manually).
There are a few BD players that can be made region free via remote hacks, but they aren't available anymore and the second hand market might be the same as the prices offered for the toshibas.
