I agree that microadjust is worth the money. I have the CJ Dead Nuts 2 Supreme Competition for 3d and it is a very well made sight. I just got an Extreme RT1000 for my hunting bow and I regret not opting for the Viper (I'm looking for a Viper now).

I like to precisely fine tune my bow so that any miss is shooter induced. I feel we owe it to the animals we hunt to make sure that we are as precise as we can be with our shooting and our equipment. So, to me, it is worth the extra to make sure that my equipment is as microtuned and sighted in as possible.

BTW, the CJ microtune is VERY nice. You can micro tune the gang adjustment and the pins. Not many sights offer that.
