Susan, you might be able to find Desert Storm surplus goggles fairly cheap. I believe there is a new model, supposedly more comfortable when worn with a helmet or something like that. I would say hit the mil-surplus sites. And don't forget Cold War, ComBlock surplus. The Russian gear is usually pretty good, and dirty cheap.

Or try the end of season sales at any ski resort. Oh, the horrors of being seen on the slopes with last year's goggles. :P
