Hello, I have a Nikon field Scope25-75x82mm it is a bit more money but worth the xtra $$'s at higher powers. I use it on the upper end of the magnification range all the time spotting mule deer in the open country nebraska sandhills.. love it! I have had a Nikon Pro Staff as well and for the money it was a good scope. Must have a very sturdy tripod for any of these to be up to standards. I have heard good things about the higher end Vortex, but not much on the Skyline. I have buddies that own the Cabela's Euro Spotter and it is a great scope...on sale you can find it for around $900. It is VERY similar to Leica model....whatever you decide i would go to the upper range of what you can afford, you'll be happy you did.
