2 suggestion on sunglasses:
Costco is now selling Maui Jim's. Fantastic glasses and the price is right.
If you want really realy good mirror plastic frame polarized sunglasses, head to a high end tool store and pickup polarized safety glasses. I use these for bike riding and of course in and around the shop. Usually under $29 for a pair, or at least that cheap here in Houston. Northern Tool carries them and you can access them on-line.

I guess no polarized, but remember, these are all ANSI rated!
