Iirc, Holosun's ir version is around 1500, and a Sightmark Wraith is around 1000. I have a Wraith, can't remember what model at the moment.
At the 4x (lowest zoom) it's ok, but any more magnification I find it un-usable. The ir illuminator however is surprisingly good, with fresh batteries it works out to 250-300 yds.
EATS batteries though.
