Extended warrantee help needed

Location : Oxfordshire Spotter Watch Member : no

My Canon 40d is just coming up to a year old and I am thinking of taking out an extended warrantee on it, but Canon do not offer anything and neither does the shop I bought it from. So with this in mind I had a look on line and found a number of companies that do offer this service, so before jumping in I was just wondering if anyone had done this or had any recommendations.

Thank you in advance for your help.
