If you are in no hurry, keep an eye on www.tramdock.com/ -- you can find some great goggle deals there at the end of the season. May also want to watch www.brociety.com/ which is snowboard specific, but also has goggles. Those are "one deal at a time" sites with a quick pace (~ 20-30 minutes per deal), so keep an eye on the deals in order to jump on whatever comes up that you want. Finally, check out www.backcountry.com/ as they are having a big sale on ski stuff right now (they also have an outlet section of the store with goggle deals).
I like Smith goggles for the overall quality and the selection of different lens types (I swap different tints as needed depending on weather). Generally, you can get a $100 Smith on sale for about $65, and see them on Tramdock for $40 or so. That sort of gives a rough distribution of prices I have been seeing for the high-end Smiths (obviously they have cheaper models as well). Last year I got some Smith Prodigy (mens) goggles for myself at the sale price, bought an extra pair when they came up on Tramdock, and then got my wife a pair of women's Smith Anthems on Tramdock too.
Factors to consider are lens tint, gender, and face size. Normally all that stuff is posted in the specs. Good luck!
