Im looking into the hha sight but there seem to be so many different types. From research, it seems as if the 5510 pin sight seems to be the most popular because of it small size. However when I look at them online, they range anywhere from $100 on up. I don't need the one that dials in to the very yard, but is there a feature on one of these that is worth paying the extra $$$ for? Forcexmple I see they have them where you can adjust the brightness of the pin.

Thanks
