One other thought to keep in mind w/insurance. I often obtain riders for expensive electronics (DVD Camcorder, Laptop, etc) even though my homeowners insurance would cover the loss if it is stolen or lost.

The main reason is that a rider does not require you to pay your deductable for your homeowners insurance. Also, the loss does not go against your insurance, so no raise in your rates. This is because you are actually paying for individual coverage of the item.

Riders are a bit expensive generally about $1 per $100 in coverage for yearly coverage. But, the lack of rate increases if you suffer a loss may negate the higher cost. Anyway, just my 2 cents worth.
