Looking For More Life Insurance

Now that I have private disability insurance, I am thinking I need to get more life insurance. At work, we just get a measly amount--can't believe how little. I don't have children, but I think I do need some to help pay for any outstanding bills and to leave to some beneficiaries. I am not really sure how to shop for life insurance.. I guess I will look online and do some research. I have seen some ads on TV, and that insurance sounds pretty good, but I feel like I should investigate it more. I don't want to be insurance poor, but you do need to have your bases covered.
