For that kind of money, don't expect very good performance, say <50 yards. If that suits your needs, then either model will likely work for you. Both will be able to be improved with an additional IR illuminator (much more powerful) such as one of the T20 pattern IR illuminators in the 800-850nm range or the Streamlight SuperTac IR illuminator. So you will be out another $60-90 if you add one of those, but they will likely double your viewing distance.
Except under good moonlight, Gen 1 and most digital scopes really require an illuminator. They come with one on them (usually), but the illuminators are often underpowered.
