I know a lot of people seem happy with the value on the Vortex, but since I have no experience I can't recommend those.
I do own and have seen many posts on the Bushnell Elite 15-45x60mm. The optics aren't as good as my Swaro's, but no $250-$400 scopes will, despite what some people will tell you. What's good about the Bushnell scope is that the design is rugged, rubber coated w/ good lense caps, and it fits into a pack very well. It is likely if you rely on glass a lot, or learn to, that you will want a better spotter later on, but this Bushnell scope may still find a niche in your arsenal.
I think you can google this and find it at a reputable internet dealer for $250.
Good Luck
