prices vary quite a bit,
i'd say try to get Frame and Forks together, it would be cheaper.....
US Frame & Forks - expect to pay £200 - £350 depending on condition, mint Chrome one's go for a bundle, and most are in the US, unless you get lucky
I'd say you could pick up a Jap TS F&F for a bit less than £200 in the US, but prices are rising....
I think the one you saw was Flanelcamel's Frame, it's Jap, I think......he's a good seller, so he may do you a deal, as i think it's been on there for a while...
go for it !!
