I carry $50,000 hull damage coverage plus the $1,000,000 liability with
Avemco. I hate writing the check every year, but I would not fly without
it. I've also noticed FBOs react nicer to renters who show up with
insurance. I don't think it's because they are worried about getting their
money back in case of an accident, but maybe it shows a sense of
resposibliity.

On a side note, a friend of mine who is partners in a 172 discovered during
his insurance renewal that he was not covered for flying a non-owned
aircraft. Apparently the insurance covered the main insured party, which is
a corporation that owns the plane, for flying non-owned planes and he and
his son and partner, as named insured to fly their plane, were not covered
for flying non-owned planes.. Not sure if I'm getting the insurance terms
correct. So the few times he rented on vacation, and the four years his son
rented at college, they were not covered.
