Of course not all but many, if not most people look at price without considering much else. Advice from an insurance broker? READ the policy and pay special attention to exclusions, limitations and restrictions in coverage. Understand what your obligations are in the event of loss etc.. For example, what if your injured during a sporting event such as scuba diving, cliff jumping, parasailing or snorkelling. Does the policy exclude? Some do. What if there's drugs or alcohol involved? Again, some will exclude coverage. Always buy insurance with the view that a disaster WILL happen.

If that's "over your head" or just too much bother, use an independent insurance broker and rely on their advice.
