I had Geico. However, when I signed up, I had terrible credit and a ticket. Also didn't have isurance for the year prior. Thus, they were just about my only option.
Now, a year later, I'm changing. Through Geico, my policy was roughly $800 every six months for 2 drivers and 2 cars. I'm switching to the company that does my home-owners insurance. Rate will be $383 every six months now.
I suggest calling around. Prices vary greatly. If you can find an insurance broker not tied to any company, they can usually run a list of many different places and help you find the cheapest.
