For a lower cost but quality scope, look at Leupold's VX-1 or VX-2. They still have the lifetime warranty but not all the fancies of the higher priced scopes.
I had a VX-1 3-9x40 on my 30-06. However, my eyes aren't what they used to be so I sold that to a friend and got a VX-1 in 4-12x40. It's equally clear but just a bit more powerful for older eyes.
