hi crossrider, are you the guy with the Tioga on the bay?
the average price for a FF set from the states to Australia would be around $60us or 30ukp which certainly is a great difference. my research when i was selling a haro frame the other week, showed a 6kg bike frame size parcel to the UK was $140aus or 56ukp. 100ukp postage for a frame is way too expensive, unless it's very desirable and can only be found in the UK, which is probably unlkely.
