Over a hundred dollars for eye protection may seem steep, especially when there are other options that can go 5 or more times less, but of all the things you can buy for airsoft, this is the most important.
I'm glad you are already looking for good quality lenses, so I'll skip that part. The added value you'll get with higher-end models with fans is peace of mind.
Fogging suck. Full stop. It will make you hate your day. Just think, if I asked you on the field how much you would be willing to pay for me to fix your fog problem right now, and for the rest of the day.
2$? 5$? More?
Multiply that by the number of games you'll play in the lifetime of the goggles, which will probably last longer than cheap crap which you'll pay again to replace, and you'll see that there is value in the higher-end models.
Also, honnestly, even if this means paying a hundred more, your whole setup will cost many times more. Wait a bit more to save a few bucks and see if you could compress in the cost of the other stuff.
Alternately, I would suggest the
ESS Advancer V12s and
Wiley X SG-1 V-CUTs. I sweat like a motherfucker and I love them.
