Ok, it's not a Tacx, it's a Minoura Mag500. They don't seem to sell that model anymore in the UK, but they pop up on
Ebay. I've seen them go for as much as £58 and as low as £42.77 (plus £18.72 postage) on Ebay. How does £45.00 sound?
@Broughtonblue, I might be able to get it up to Leicester over the weekend, as I have a friend that way who will be passing my door.
