SERIOUSLY P****D OFF

Three days and my Camera, the one where the repair shop could find nothing wrong, failed again today, the local camera shop I think is a bit useless so come Tuesday I'll speak with Canon direct to see what options are open to me, another string would be to find out what protections I'm afforded when buying from an eBay 'shop', just under £500 is a lot to pay out for something that doesn't work whether new or second hand!
Went to Leeds today, the new Victoria Centre is very nice, got to take five photos before it all went wrong so this is your lot.
