I've been interested in some time about investing in a night vision scope and been looking around and I have found that for my price range I have two options: the Yukon photon RT or the ATN X sight 2. They are both similar in price, however the ATN is slightly more expensive out of the two. I've seen them both on airrifleshop.com. I'll leave the links and id love to hear people opinions on what's better, as I'm not fussed paying more for the x sight, its just I've heard the photon RT is mint for the money.
