Qanba JLF Microswitch UK / Europe.. ??

My joysticks playing up and the microswitch on the down direction is a little off, where can I get a replacement microswitch from ?

I think its a Sanwa MS-0-2P.

The postage fees from some places Ive seen is very high for a 5 gram microswitch its either £3 or £8.

Any place have them cheaper ?
