There's no problem explaining the merits of buying a $3000 scope. I believe the only reference to the more expensive scopes were also done with reference to lesser expensive scopes that may work as well. If you are shooting at 1000 yards and only 1000 yards some of the more durable, higher cost options probably aren't needed as you aren't going to be cranking through the adjustment range a ton. I do like the fixed magnification models for their durability and better glass for the dollar. That said, at 1000 yards, on days with a lot of mirage, being able to dial some magnification out is a great benefit as well. As long as you stay in the $500+ range I think you should be ok, with the more you spending adding to more and better features.
