Hello I will soon be purchasing a Canon HF100 of Amazon On the page in the related accessories section there is a extended warranty package I have some questions about the warranty- Does the HF100 come with warranty already? Do I have to buy the extended warranty at the same time as I purchase the camcorder? How will I activate the warranty? Is it actually worth buying the extended warranty? Thanks a lot. EDIT: After reading the terms and conditions of the warranty I have discovered that it does have to bought at the same time as the camcorder.
