I've compared my razor side by side with my buddy swaro. To my eyes the swaro had just a slight edge on clarity, and I mean really really slight. Not enough that my buddy could tell, and we both agreed that it's definitely not worth the price difference.
either way, I've got both the 30x wide and the 20-60x zoom eyepieces. I keep both but the only one I ever use is the 30x wide with the mil reticle. It's an awesome spotter, worth every penny.
Got mine from Scott at Liberty Optics, good guy and would definitely reccommend.
