I agree, they are good for low light, I don't currently have one, but have seen them and they look like exactly what I want and need myself. I also hunt a low light area, especially in the mornings when the sun is coming up behind me. I will probably buy one for next season, I just didn't get around to it this year, had a new bow that I was more worried about obtaining accuracy with first and foremost!

I'd definitely splurge, I wouldn't get the $20 one though, I would go for a little better quality one if I were you, I've looked at both, and I'd rather pay more to have a better made one with better, heavier quality and more durable systems in it, I'd hate to turn my knob and the light not come on with that 8 pointer right there!
