A friend just bought a Pacific DVD2002 (made by Schneider) from ASDA for £39.97. It seems to play everything, build quality is fine (especially for the price), the picture and sound are also decent. It was easy to make multiregion through a handset hack.
For this price, it is almost disposable and they have an even cheaper player for £29.95 - a pacific DVD2001. The build doesn't look as good and it doesn't have a display but reviews credit it with a good PQ (apparently MR out of the box as well).
