Taaa Daaaa!
Thanks for the segway, Hardstalk
That is a great deal on the Zeiss, but the Razor will actually outperform it due to aperture advantage (85mm vs. 65mm). The Razor gives up little, if anything in optical performance to the "Big Three." The Zeiss will save you some weight and bulk, and would be the better choice if portability was a big concern. Either are excellent spotters, and I have owned and used both extensively (although my Zeiss 65 was the older silver model with the older zoom eyepiece).
That is my take.
I'll be here all week, tip your waitress, etc. etc...
EDIT:
The Swaro spotters in that price range are the non-HD spotters, and are very good, but show significantly more Chromatic Aberration than either the above Zeiss or Razor.
