A step above the diamond back version - Vortex Viper HD 20-60x85mm Spotting Scope

While nearly twice the price of the 85MM Diamondback version, there is a noticeable improvement in clarity at higher magnifications. It's not a night and day difference, but definitely better and more significantly, the chromatic aberration at 60X is almost non-existent in comparison.

That may not be worth the much higher cost to some people, but when you're glassing past 500 yards or looking at astronomical objects, better glass, is well, better. I did not see nearly as much difference comparing this to the razor so this scope fits the bill.
