The reason I ask is that really must take my 70-300 IS in for its "recall" service, never had the time but must do so soonish 
The other reason to ask is I thought I would take my 40D along for them to give it a sensor clean - dust showing at f9 aperture and I like taking airshows when I can get to them so dust at such a large aperture is a no-no IMO.
So apart the fact that the lens 'repair' will take a few days/weeks (I hope its days) how did you find them for sensor cleaning and was it done as a courtesy like our USA cousins seem to get done at their respective Canon service centres?
Also, did they get it squeaky clean and do they show you the results to prove it? Going to Elstree though in miles is a shortish drive but round the NW sector of the M25 is no fun at the best of times
so I really only want visit as absolutely necessary.
maybe i should take a trip there next time!
