Recently, I purchased the Nikon D60 SLR and I also bought a 2 year extended warranty. I have 30 days to make a decision as to whether or not I want to keep it. Do I need this? I am not clumsy, although I know accidents happen. It cost $224.00.
I bought it at Ritz camera.

Your two year extended warranty might not cover accidents. Make sure if you decide to take keep the warranty that it covers accident.
That's a tough decision, one you have to consider the type of activities you do when taking pictures. I myself, didn't buy an accident warranty for my DSLR camera (haven't had any accident since I had my first camera when I was just a kid – and, I'm sort of clumsy and accident prone but always aware of taking care of cameras). But I bought one for my niece on her Point & Shoot camera, assuming what her friends are. She is a careful kid, but she are around kids her age, and you know how they get.
If you probably going to take your camera to a beach or campsite, I would suggest it because they are not as sturdy as film camera when exposed to sands, dirt, and water. However, if you have been always careful with such equipments (not just cameras), you can just skip the warranty.
