Renting ?'s

$25k of hull insurance?

Sure. It's what I carry. A nice Cub can be had for under $30,000.
Besides, the instruments will probably survive the crash

My instructor carries $15K. He's even more optimistic about systems
surviving than I am. Besides, he reckons that he can risk some of his
own money in there.

(We don't have a minimum. We are required to be insured, that's all. I
think the airport is mostly interested in covering its own deductible;
it will let the two insurance companies argue about the details.)

all the best -- Dan Ford
