You need to consider how far you are planning to shoot with it. As mentioned above, its really all about how far you can identify your target. I have a hogster 25mm and I really like it but to me I its a 100yd thermal, maybe a little further at most. I have not looked through expensive thermals so I can't tell you what they are like but with the lower end thermals, the lowest power setting will be the clearest and it degrades rapidly from there. When I hunt, I never take it off the lowest setting which is a very crisp picture and I am very happy with it. I tried the 2nd setting and it just lost too much clarity but thats just a personal preference. You can crank it up but at some point you will be shooting at unidentifiable blobs. The point being that if you plan on shooting a couple hundred yards across a field, you won't be happy with a lower end thermal. If you are hunting 100yds or less, they are fantastic. I was trying to decide between the pulsar and the hogster and ended getting the hogster on sale for about the same price as the pulsar. The specs of the ATNs look fantastic but they make me nervous. I have never owned one but they have gotten a bad reputation. I think it is due to poor customer service as well as releasing their day/night scope with so many bugs. My understanding is that they have worked them all out and their newer models are worth the money, Their thermals are all new lines. Have they worked all the bugs out yet? The other thing I don't like about them is that they have an internal battery. The hogster and I believe the pulsar both use 2 cr123's. The hogster can handle rechargeables, not sure about the pulsar. Rechargeables are a slightly different voltage and can damage a thermal if they are not designed to handle them. The hogster has a setting for rechargeable or not.
