Bought them. They are worth it!
HD-Bs have more bells and whistles and can range further but they don't range as well on shorter archery targets.
Thomas, do you have the newest "R" model or do you have the HD-R model?
If they are the "R" where did you find them? They aren't even listed online (Euro-optic, swfa, Cameraland etc.) other than Leica's website.
