The Mico is no longer, the Dansai is very hard to find at Tesco and the Kiiro is out of stock at the moment but I think it has been replaced?. There was a Bush and the old Pacific from Asda was but not sure if still available?
You can buy "Chipped" DVD players which are region and macro free but they are over £100 though
I just found a Mustek 560 DVD Player with macro free for £130 below. Not sure if its any good though?
