You cannot buy a new region free DVD drive (a.k.a. RPC1 drive), but some of them can be made region free with certain (unofficial) firmware.
You can get region free firmware for Optiarc drives as well as Pioneer drives.
I'm not sure if the LtnRPC utility can still be used to make the newer LiteOn drives region free - perhaps someone else can answer that.
There may be other drives that can be made region free.
Even though your drive is region free, you will need some way to circumvent region locking in many DVD software players.
