Something to consider that may make things a little cheaper. You don't need a 24X scope. I had a 22X Nightforce and sold it for the 15X FFP. Now, I know that the Nightforce is probably out of your price range. BUT I am extremely pleased with the decision to go with the 15X. You'll have no problem shooting to 1000 yards with a 15X scope.

That being said, if you go with something with more power, I would go with the FFP for sure. The mirage will be awful at 24X, so you'll probably be using the scope at a lower power than max. That's when the FFP would be nice since your reticle probably won't be accurate other than at the max power.
