Like Alan says no you won't get a vantec repaired. And the state of play as I understand it is that Vantec have halted production of the big end speedos. A wotty is a great controller and you can get repairs in the UK, a roboteq will require sending to the US. However the roboteq does have a track record with mags, did Big Nipper try a wotty in it at some point?
