Merlin has gone to exactly the same place as I would have done to buy a multi-region DVD player. (It's where I got mine from).
However all DVD players are initially manufactured as 'multi-region' and then 'locked' to one particular region. Removing that lock is usually a very simple process (such as opening the drawer and entering a 4-digit code via the remote control). So, before you buy a new DVD player, tell us which one you've already got. We might be able to tell you how to unlock it.
