I have farming insurance company and my policy went from $400+ to $1600. I wasn't able to find anybody in time last year, but I'm just waiting for the renewal to come through in the next month or so and I'm leaving them. who knows how much they will increase it this year.
I did find insurance co you mentioned and and got a quote from them and it was only for $1K and like double the coverage I currently have. You can also play with the co-payments and other amounts to bring down the price.
