I'm with Irulan on this one. So far I have only bought what I could find cheap at Wally World or Gabriel's. I do get the polycarbonate lenses so they don't shatter, and something polarized 'cause since I had my eyes "LASIK'd", I find Glare much harder to deal with.

I'm sure one of these days I'll break down and buy a "real" pair, but so far I've been able to find other things to spend the money on !
