depends on the wording/coverage you like....
If you want liability only, you choose the amount, and I think C-PLAN and Marsh were within a few percent of each other.
I got 2 quotes last year for full hull and in motion, IIRC, the best price did not have the $1 mill passenger coverage, so I asked if they couldn't offer combined limit, giving the same effective coverage, in my opinion. It took a few days, but they came back with that, at the same price.
...so don't hesitate to ask for what YOU want, not just what they are offering, especially this time of year, they have time to cater to you.
I planned to fly into some grass strips, so asked to be sure there were no exclusions buried in there anywhere.
Pete, PM me if you'd like, I can dig up more detail.
