In reply to Mike-W-99:
I'd go for option 4.
If your camera has a well known fault and its less than six years old, why not exercise your rights with the Consumer Rights Act?
I did this with a Sigma lens that I bought from Jessops years back. It died after almost three years, when the mechanism fell apart inside the body.
Jessops started off with the usual, sorry its out of the 12 month warranty. They then asked if I bought an extended warranty, to which I said no.
If you stick to your guns and exercise the Consumer Rights Act, and you are patient because this can take months, you should either get the camera repaired or replaced. Yay
