I've had good luck with $60 Tifosi Forza FC (Full Coverage) and $5 lawnmowing safety goggles from the garden store (in nice rainy-day-contrast yellow).

And I've been told that the lawnmowing goggles look sexy... They really don't look bad at all, and the lens quality isn't poor. My glasses mirror fits on them just fine. And if they get lost, well, I won't cry too much.
