Darryl - could also try WM Snell at Alton.
Bit further for you, as they are off the A31, but quite a few Londoners use them, as they are on the mainline railway (200yds walk from shop!) and its a nice ride there.
Good old fashioned family outfit with great courtesy & service
Also should save yourself about £200 or so on the price!
