now i don't live in the uk so taxes, i am not familiar with, but freight is usually between 150 us to 200 us depending greatly on how they pack it. i have gotten 6 bikes from US to norway over the last five years (which is dearer than UK) and as far as taxs go i believe all european taxes are basic value added tax up here its 25 percent. If the seller is an agreeable chap you can get em to mark it as a present with a big birthday card slapped on the side,and you don't have to pay tax ,which worked once for me, or pay for item in two seperate payments one large and one small and ask seller not to send a detailed invoice with the item just details of who the sender is and what it is (used bicycle parts), then customs will contact you and ask for proof of purchase which you promptly fax to them,a receipt of the smaller amount (must clearly match senders name) of course and say thats the only document that you have, but you can contact seller for additional proof of purchase if need be , has worked for me. But beware of bidding on the bay over there as sellers often try to pull one over on you ,a good site to visit is usps.com they have rates posted for every country just to get a rough idea of if your being gipped or not, i have to say that in my cases its been worth it as norway is shit expensive and they don't stock anything good but check your local prices add the freight 75-100 quid and 20 something percent duty might be worth your while might not ,good luck.
