The right way to do this, is to get an endorsement for your home owners or renters policy. I know you got some conflicting info, but it most likely came from non licensed people in the office, like a secretary. There's a few exceptions, but for the most part, its not legal for do discuss insurance policies with a non licensed person. (They can get in trouble, not you).
If you chose to insure, here's a few tips that may help.
-It is extremely important to accurately value your equipment prior to purchasing the endorsement. Don't play games. If you insure a $500 item for $1000, not only is the insurance company going to fight it, its against the law.You can't make money from an insurance claim.
-Along with proper valuation, make sure all details are gone over before then indorsement. Pictures, receipts, serial numbers, etc... Also, take the agent out to your car and show him everything. If you have a claim, your agent can verify that he actually saw the items in the car, when you speak to the claims adjuster.
-This is most important. If its not listed in black and white on your insurance policy, you're not covered. Insurance goes by whats in writing first, and verbal second. Always assume the insurance company is looking to screw you. If they don't, think of it as a bonus.
-Make sure you have an uninsured motorist endorsement on your auto policy. I know I said you don't recover anything from your auto policy, but in some circumstances, a 3rd party may be responsible for paying you damages. Like if you're in a car accident that's not your fault. Simply put, you're buying an insurance policy for someone else, in the event they don't have enough coverage.
