I think a lot of it has to do with finding the scope that works with your eyes. I know one gentleman on here said have your eyes checked by Doc., this may be an issue, but being a guy that has to have eye glasses I know it can be finding the right scope for you. Optics are just like eye glasses they have to match your eyes or they are not going to work right. I like Leupold and Vortex the best but have had good Bushnell and Simmons, on the latter two you can see a difference in their very low end scopes and the better ones. I have not looked at the high end scopes even from Leupold and Vortex as they are out of my price range. So I look at scopes in my range and go with the one that I can see the best with. There are a lot of other brands that are very good scopes and some people with tell you if you don't buy that brand you are not getting the best scope, that may be true form them but not for some others. For an example I had people telling me to get a Nikon (witch are very good), but I found Weaver, Vortex, and Leupold to be better for me. Just remember others are being very helpful and there recommendations are good to look at but compare and pick the one that works best for you, it may take some time looking at as many as you can to find the one that fits you and the task you want it for. Be patient so you pick the right one. Good luck and have fun.
