I work with a bunch of Europeans here in the US and although most of them have DVD players, they were unaware that a lot of players can be made region free. Now I've looked through the hacks and tried crossreferencing them with what is on sale at the big stores this week, (they'll not be wanting to spend a great deal of money as they've already got one DVD player for R1) but is there a general consensus on which the easiest available DVD player that can be hacked without any worry over whether the version of the firmware might be the one version that isn't hackable. Someone has the Apex 500b that has the only type of chip that isn't upgradeable.

Thanks for any help
