Anyone know where to get Cheap Auto Insurance around here?

My auto insurance just renewed and the premium went up again, even though my driving record is clean. I’ve been trying to shop around for cheap auto insurance in this area but most of the quotes don’t feel much cheaper than what I already have. I want something affordable that still gives decent coverage because I drive a lot and can’t risk being underinsured. Do folks here usually find better deals with smaller local agencies or do the big companies actually offer good rates?
