I agree 100%. Every scope I've bought in the last 3 years has been illuminated. Dark reticles on dark animals like buff, bears, etc are so easy with an illuminated reticle. To the point being made about brightness, I prefer a scope like Swaro which when switched the left is on the low light setting...to the right on the day time setting. Each can be adjusted easily. Hand to God, the illuminated reticle has helped me take some of my best trophies in poor lighting conditions.
I've never had the battery wear out but even if it did, the reticle is still there. Replace them every year or two and I've never had an issue. Saying you don't want a battery there (with the current technology) is like saying you don't want a rangefinder in your binos. Why not? It's great technology. Even if I was hunting with iron sights, I would still want to know the distance...especially with irons. If you haven't tried the lighted reticle, give it a try sometime. It is very helpful and truly helps make better shooting in poor conditions, which can happen any day on a hunt.
