If you have a Gen3/4 timmy, then I highly recommend getting the Tadao Yakuza OLED board. It is an awesome board with loads of up-to-date fire modes and software. It uses push buttons instead of the very delicate and fiddly membrane pad. Check out the links below...

They do ship internationally from the USA to the UK. But it can be expensive, and there's always the chance that those great guys at customs will slap import tax/duty on the board when it arrives.
Alternatively if you want, approach the great guys at LiPS paintball store, as they stock Tadao Yakuza boards. Their website doesn't display timmy boards, but if you ask them kindly enough, they may be able to order one in for you.

But if you don't really want to fork out the cash on a new board, then I'm afraid your stuck with either trawling through ebay, and BST threads on other forums to see if you can pick up some new membrane pads. Or, as stated previously, Virtue stock "upgade" membrane pads. They don't do anything special, they just have fancy logos on them.
