+1 on DWI.
Only problem is the RMA takes a while (took 1 mth from drop off and pick up from their office) and my camera came back with a shoddy job (body parts not aligned properly and focusing screen was massively dirty). But they did honour the warranty and fixed my Error 40/30 on a 7D. My recommendation is to buy the MACK warranty which brings it to 3 years coverage by Canon Australia.
