It's just like when buying a pair of ski's or ski boots. If you spend more money you are going to get better goggles. Sure a $50 dollar pair of goggles would work, but they will probablyfog up on you, the lense won't be as good of quality and they will break easier. You are going to get more bang for your buck if you spend the $100-$200 when purchasing say a nice pair of Oakley's. The lenses will be top notch and the overall durabilty of the goggles will be great. They wont fog and if you take good care of them they will be great goggles for a couple of seasons. I've had a pair of Oakley Crowbars that I've used for 5 seasons now. So the more you spend on goggles the better goggles you're going to get.
