i found another site that sells them: http://www.applestone-music.co.uk/shop/prod353.htm
i went with a generic MM pickup in the end, off ebay aswell
i got some wilkinson tuners for the bass i built, they look very nice but they are a bit stiff, its definatly budget stuff.
I didnt realise the tuners were wilkinson until i got them , because they were advertised as just brandless black fender style tuners
ALSO, if you ever see "vintage" basses(the brand name), they use wilkinson pickups exclusively, i played a jazz copy a while ago to see how the pickups were, and they were pretty similar to the standard MIM fender ones
