I like the Sightmark Photon 4.6x XT. It sees very well at night and is priced a little better than the Pulsar (less than half the price). I bought mine for 500. I've used the ATN X-sight, and the Pulsar N750 and I think the Photon XT is a better scope especially considering the price. They are a bit tough to find available so I am told. I got mine from UNV shortly after they came out. I've used it a lot and killed coyotes at night and in the daytime with it. Only thing better in my opinion is gen3. As with all digital scopes you will need a good IR light source. An 850nm T20 would be a good choice to use with it. Lots of other good choices out there too. HTRN and UNV both offer good options.
