i just got a quote to replace the entire shutter assembly in my 1ds mk3, $350-400 nzd (about 150 euros).
with cps, a 3 day turn around for repair.
One thing I miss in the digital age is the small repair house that could fix about any camera.
Every photographer I knew had one of these go to guys in every market. I used one guy named Larry Work (no kidding that's his name) that would meet me at the airport and fix a shutter or a lens while I waited to change planes or loan me a spare whatever until he got it fixed.
Now we file a repair case with the dealer who files a repair case to the maker then sends it off to wherever and get a stock price of $3,140 for any fix, even a watch battery. Larry would laugh his a** off on that one.
Then again Larry always had people lined up waiting for repairs, good economy or bad economy so there is something to be said by not overcharging.
As far as costs, in Hong Kong Canon replaced a sensor and recalibrated one of my 1ds3's for $1,000 U.S. and did it in half a day.
(It was user error not the Cameras fault and it's a long story so . . . )
The last Canon shutter I had go out was a few years ago with a 1ds2, out of warranty and CPS in California fixed it for free, overnight to them and back to me the next day.
A few months ago an assistant dropped my 70-200 and I thought it was done. CPS fixed it for $170.
