I thought the VB50 does both PAL and NTSC? If it doesn't, you can look at the ProV (it does both) although it also has the tuner built in (you can of course just ignore the tuner). If you really don't want the tuner, you can look at the soon-to-be-released BriteView (big brother of ProV). It offers component in and out (which neither the VB50 nor the ProV offer) but it will be quite a bit more expensive than the ProV (maybe 2x or 3x).
if not and you wanted to save a few quid a friend of mine has a pro-v that he bought to play his consoles on a monitor, it is still sitting in the box and i know he hasnt used it so he may be willing to part with it.
i will ask him for you if you want, how much are they new ???
