Anyone care to recommend which insurance company they're with for aircraft
ownership?

I've gotten a few quotes, so far the lowest has been through AOPA and their
process. But I wasn't too impressed with their payment options. They
either want the entire annual premium up front or a large bulk up front then
either montly or quarterly payments with finance charges. On top of that
they won't accept a credit card as method of payment.

Anyone using a company this has more payment friendly options?

Thanks.
