Another option in the same price range is the Sightron SIII. They don't advertise as much as NF and Vortex but their product is solid and the glass is very good.
Not sure if you have made your purchase yet but my vote is for NF. The 56mm objective is overkill but the glass is excellent.
The Vortex is a nice scope but where they fall short is in low light and low light looking into the sun. This is where most scopes fail. You get what you pay for.
