For a gen1... this is the best of the best - Armasight Spark G CORE IIT Night Vision Goggle

Best gen 1 monocle out there and the skull crusher is actually very comfortable... If you know the basic of how to use night-vision you will be pleasantly surprised. I have only used this out to 50 yards and it is great. much clearer than other gen1 i have used. About the same as gen2, but gen 3 the difference is very noticeable. The included illuminator is just OK. I found myself using a mounted IR light on my Tavor... I also use this with an IR laser and it serves its purpose well. i was ringing steel from 50 yards no problem with this and the laser in complete pitch black darkness... but doubtful I would have been able to see that far without the separate streamlight illuminator. For the price its a no brainier, spend an extra $50 on a good illuminantor.
