Rusty, why do you need insurance?  Aren't you paying for your aircraft up front?  If you've not sunk a year's wages in borrowed money to build the plane, what liability is there that you can't pay for.  It appears that hitting something expensive with a crashing airplane is a very difficult thing to do.  Nearly all the off airport accidents I've heard of result in a bent up airplane and a very few bent trees.  I just don't understand understand the driving need to spend thousands a year that could better be spent on gas or recurrent training.  I still think the biggest risk in general aviation is the nut holding the stick.  In the long run, $1500 of training or just keeping current will pay me back much more than the equivalent insurance.
