I had Allstate and they were cheaper than Progressive by a good chunk for me but, not the cheapest and not as well known for service.
I would see if you can get Erie insurance. IF you dont believe the internet then stop by or call one of the better bodyshops in your area and ask about Erie. Also progressive cant do the combined discounts since they didnt offer homeowners last I checked. Good luck.
I use stat farm because we have multipul policies with them check the co you get your car insurance from. Tell them you want something good and cheep or your taking all of your business elsewhere. I don't remember how wuch it was but i do remember my agent showing me she could do better than anyone else!
