I have no experience with pride Fowler. However I do like the BDC on Alpen scopes and Vortex scopes. My FIL has an Alpen on his win 70 300 win mag. He has used the BDC at 600 yards, on the money. The glass is about the same as the ziess, perhaps slightly less bright but very clear. The Vortex Viper series starts at close to 400$ but its worth saving for. I have 2. Both are clear and bright. I haven't been able to shoot them past 200 yds yet, but the scopes will do better than I will at long range.
