So I just got my 1dMkIII camera back from a CPS cleaning, the turnaround was pretty quick (I shipped it 2 day service last Friday so they actually received it Tuesday)
I got an estimate for other repairs I wanted done on Tuesday afternoon, it was fixed yesterday, and I received it today. I asked to have the dust cleaned from the viewfinder which was done and everything looks good and works well 
There was however a little stumbling block:
Back in October I decided to order a door for the CF Card as the rubber was peeling back and it wouldn't "spring" open on its own. I ordered it direct from Canon for $34 but found out it wasn't easy to replace so I put it aside and sent it with my camera this time to get an estimate to have it installed. Mind you I bought it from Canon and it was still in the Canon parts bag with the part number label still stapled to it the way it came from Canon.
Fast forward to Tuesday when I received my estimate. There was a charge for $34 for a "part". I called CPS to inquire what this "part" was and I was told it was for a CF door assembly.
I proceeded to explain that I had sent a BRAND NEW Canon part with my camera and was quickly told "Canon will not install customer supplied parts". What
? I explained the story that I bought it from Canon to install myself, etc etc so the CPS Rep put me on hold to go and find out what she could do.
She came back on the phone - "Canon will not install customer supplied parts, they cannont be warrantied" Ridiculous. I even told her to write on the invoice they won't warranty the CF Door. The answer was still NO.
I then asked to speak to someone higher and I got someone from Management on the phone who was VERY pleasant and explained what she's heard about my problem so far etc etc. I told her it was ridiculous that I should have to pay for something twice. While she agreed there was nothing she could do about erasing the cost 
She DID however say she could offer me a Canon accessory free of charge to offset my financial loss - she asked how would I like a new battery for my 1dMkIII !!!!!!!
I made out OK with this as I know a new Canon 1dMkIII battery is worth much more than $34 
All in all CPS made it right and I am happy !!
