Best steering lock for a Defender?

[philcray]

Hi

Never thought about this before but getting a bit paranoid now that the Daily Mail is reporting on the surge in thefts of defenders....

Does anyone have any recommendations on the best steering wheel lock to buy, the car is a 56 plate td5 90XS if that makes any difference. Halfords have this one

probably at the discount end so are dearer ones any better, any feedback or recommendations much appreciated.

Thanks

Phil
