++ for the Kowa 821, but it is not cheap. I bought it with the 27 power LER because I wear glasses, works great at 300 with 30 cal, and well past 500 with 45/70. I also bought the 20X60 eyepiece for it on sale at optics planet, it also works great, but more power is no always the answer. Had the Konus 80MM and it is a good scope for the money, but not up to the KOWA, BUT it is 1/4th the cost.
