This subject comes up every so often, and always it seems that the Progressive insurance company gets touted - even by me. That's what I have and the rate for a $50k agreed-value policy with their recommended liability levels was $220 last year. That is down from $400+ the first year, I guess because I have never used it.
Since T.R. invited the insurance pros to chime in, I'll post my policy particulars for an assessment. (Cut and paste from my info online.)
