Many people (not all but many) would rate ATN at the bottom of the list as a company in the thermal space ... I've owned some ATN gear continuously since Feb 2013. PS-22 nv clipon ODIN 17mm 1x 320(30) and Thor HD 384 19mm 1.25x ... I still own the ODIN and use it all the time ... it works well for me.
But the Thor HD was unfinished IMHO. On black hot there was not even an image, just a solid white screen. It was fuzzy image and very fuzzy beyond 100yds. There were other issues as well (documented in my practicing thread). I called ATN twice ... .the first time they told me to download the latest firmware and try again. I did and the new firmwear did calibrate the digital compass like the instructions said, so one step forward. But the other issues were not solved. Second call to ATN they told me to return it, I did.
Those 2 interactions with ATN CS were the 2 good interactions I've had. The other three (on the PS-22 and ODIN) I would characterize as "hostile" ... on the part of the ATN CS people on the phone.

So in summary, while a few people have had good results with ATN ... I think the majority (and then some) have not. CS is not good. And they tend to release unfinished gear. The "X-Sight mod 1" was another example of unfinished gear.
For $3k to $4k you are in Pulsar territory and that's where you will get the most bang for your buck.
The Trail XQ50 is comparible to the ATN model.
