Mike,
I bought a cockpit cover and wing/tail covers from airplane-covers.com. The covers are coming up on two years old and still look very good. The fit was excellent and they come with a standard two year warranty or a three year warranty for Sunbrella fabric. I use the cockpit cover 365 days a year and the wing covers for approximately 5 months a year. I paid a total of $511.90 in December of 2007. (including shipping) The cockpit cover covers all the glass and the fuel caps.

I will be going to Old Rhinebeck next week and I will bring the cockpit cover if you would like to take a look. If I don't bring a passenger, I can also bring the wing/tail covers.
