Whats the cheapest car insurance company in Missouri?

I am 20 and attend college. I never needed a car before but now that I have to start driving, I have to get my driver's license. I have my permit and a car but since I need legal tags and insurance to take the driving test. I have to get insurance before I can get tags. So I wanted to know whats the best insurance company for me, where prices won't be outrageous??? Thanks for the help: )
