I have an ATN gen2+ NOD. It's their PS-14 line, which means it's got smaller lenses on both sides and uses a russian tube that actually has zero blemishes or dead spots. If I could buy a replacement objective lens, it would be a perfect example of how russian gen2+ can compete with low-end gen3. No edge distortion, autogain, and over all a very nice device if you can't afford gen3. I couldn't at the time. I have good omni VII gen3 now. HOWEVER: I tried to contact ATN to get parts. They were totally unhelpful after I waited on hold for 47 minutes to talk to someone who could answer questions. They couldn't look up the serial number, and argued with me about how it probably wasn't an ATN device. You pay for what you get.
The question was "Is the ATN X-Sight worth $700." It was answered. "No, it's not."
The second question was "Is the pvs-4 a better option, since thermal won't work for me?" It was answered. "Yes, the pvs-4 is an awesome device."
I think we can all dispense with the ATN-stories about how good or bad of a company they are, it's pretty evident to anyone who doesn't have a stake in their success or failure. My question has been answered four times now. My money will go towards a pvs-4.
ETA:
Sam, Dino, westernhaikus1, Caver, ZeroFX: thank you for your input. I'm gonna pass on the x-sight, again.
