hey,
i can find out tomorrow if you want?? dont know how much stock the uk importers carry for older models, but if so i can get a price for you? (cant be that much)
I emailed Fisher earlier and after being routed through the LBS I think they are about a tenner, so I might just get one through them if no cheapo ones appear before then.
I presume you are at a bike shop/ distributor then?
