Topic: Are minidisc music players region locked?

[Urusei0Yatsura]

I'm thinking of buying one to listen to anime original sound tracks. Also does anyone know of any good anime ost minidisc sellers that sell from the United Kingdom?

If anyone knows where to find Death Note, Detective Conan (Case Closed) OSTs please tell me.

Note: For people who don't know minidiscs, whilst not taking off here in the West have become a popular as CDs as a replacement for casettes in Japan.
