Free: Contests & Raffles.
If you are planning on shooting at the extended ranges the cds is much better. The b&c works well but not as well as the cds when matched with you gun. My all time fave is the 4.5-14.
SO now i am looking at the Zeiss, Nikon Monarch and the leupold. I like the conquest with the z600, and z800 reticles. Man reading reviews makes the zeiss sound like the best option. But i like the american company and having leupold close.
