There are tons of Goggle comps out there,for sure shop around and see which offers what you are looking for. Style, fit and conditions you are riding in? Some comp give you 2 lenses when you buy them, for sunny and cloudy days. Spherical goggles are real popular right now and also pricey, so if you do go that route make sure the lens is perfect for your enviroment..
Also new lenses can cost as much as a new pair of goggles so do your homework, also if you keep the foam lining part of the goggles against your face and not on your beenie that helps with the fogging..
best of luck.
