I had the 30D into West Photo for sensor cleaning two weeks ago and it came back acting wierd. They aren't claiming any responsibility for what's going on with it. The shutter button is lagging and then not working at all at times. It will auto focus, but then has to warm up for several shots before the shutter button will start acting normal.
I sent it in for repairs, and had to reserve another 30D as a rental for a wedding I have in two weeks. They didn't even discount me on the rental. Grrrr. I'm not happy with them at all, but I don't know of any other shop in town that does what they do.
