RE: Adding a Scope
I, currently, have Zeiss Conquests on almost all my guns. I used to have Leupolds on everything but have been replacing them as I can afford to. My dad is a sales rep. for Zeiss so I haven't had to pay retail, and that makes a BIG difference in what I can afford to use. I just ordered two more 6.5-20's and am probably looking at around $400 each which is not bad for that quality optics.
From a dollar and cents point of view, I have killed more game over the years with Tasco optics than any other brand. They are far from the best, but sometimes economics takes precedence over quality. My dad used to rep. Burris, and I bought a few of them. Their scopes do not fit my eye, so I switched to Leupold which I like very much. Since I have been shooting Zeiss for a couple years, I like them better because they do collect more light early and late than Tasco, Burris or Leupold.
This is only my opinion, and I will not argue what others prefer or think is best. To each his own.
