Dunno what to tell you, mi amigo. Wireless is alright, but not the best for gaming. Give me a wired mouse any day for that, especially my Razer.

Logitech makes some good wireless combos, as does Microsoft and Kensington.

Here's some links. I know that they are NewEgg, and that NewEgg doesn't ship to the UK, but they will give you an idea.
