I have the Banner 6-24x40 mounted on a 300 win mag. It's been on there for 4 years and is still holding it's zero. For the money it's pretty clear and durable. As someone else said it does get a little darker at the higher powers but all high power scopes do that, even the expensive ones. Granted a more expensive one will be brighter than the Banner but if I need a brighter sight picture I just turn the power down a little and it works fine. I also really like the Swift Premiers, you may want to consider one of them as well. They have fully multi-coated lenses and are very bright and clear for the money albeit they are more than the Banners.
