Best/Fastest Canon Repair Facility?

Hey there,

My 10 month old son pulled my 10D/17-40L off of a table today. Now the A/F on the 17-40 won't work. I have also been receiving intermittent ERR99's for a while so I figure this is as good a time as any to get it fixed.

Anybody have feedback on the best/fastest Canon repair facility? How long is the turnaround usually?

Thanks,

Chuck
