IMO if you want a one and done then go with a dedicated thermal. You don't have to spend $5,000-$6,000 on an expensive 640 or 1280 to go out and have fun and kill critters. You can get a good quality 384 for less than half of that and go out and have a good time.
With that said, if I know I'm going to be hunting open areas/fields I still like to take my NV out.
