good landy garage in north Surrey / SW London

Can anyone recommend a good garage in Surrey / SW London? The fella I used to use retired (possibly on the proceeds of fixing my landies) and I've just lost patience with the my local non-specialist garage. So ideally I want someone who knows one end of a landy from t'other, and doesn't charge a fortune.

Near Reigate, there's AJS on reigate hill - don't be put off by the website advertising tyres - they know what they are doing, and are good at it.

Thanks. Funnily enough I think I bought some tyres off them some years back, and if I ever realised they did more than that, I'd forgotten.
