The Nikon ED50 and Vortex Razor HD50 are both fantastic little spotters. I've looked thru several ED50s, with every eyepiece available, and own the Razor.
The Nikon offers more eyepiece options. The fixed 27 is very, very easy to use and actually my favourite setup for that scope. Questionable warranty/service with Nikon...
The Vortex, in my opinion, has a slightly better view. Slightly. The fine-focus is a lot nicer feature than I figured it would be. Hopefully it'll never be needed, but Vortex has a good warranty...
If the 50s fit what you need to do, it's hard to go wrong with either scope. IME.
