I am thinking of selling my Canon G12. Bought new last year from John Lewis for £380. Will sell for £125 because there is a dent in the magnesium body from when it fell out of my camera bag 2 weeks after buying it. (see pic) All functions work as new, it is purely cosmetic. It can be as complicated or easy as you want. Put it in auto, and it will still take superb images, or play with the huge array of options to obtain various results. There is also a tiny spec on the lens that is far too small to see in a photo, and doesn't show itself on any images. It will come in original box with all the discs,cables, charger, booklet etc. it was supplied with. The only alteration I have made, is to the neck strap, which I cut and turned into a wrist strap (works great)
I'm sure the guys on here who have/had one of these will vouch for how good they are. And I am sure when you do a search on second hand G12's, you will see how cheap this is.
