Once you get down to that level, you might as well just buy the Joytech/Novatec hubs from whoever has them at the best price on the day. Planet X have them at £19.99 each, so about £55 for two hubs, sprocket and lock ring. If you look closely, you can see that Token have very sensibly subcontracted their hub production to the specialists at Joy Industrial Co. Ltd just like everybody else. If you are a Wiggle Platinum customer and have a voucher code, I think you could save 10/- compared with On-One, but you'd have to wait for them.
