Had the Vortex Skyline 80mm (not ED), Swarovski 80mm, and Nikon Earth/Sky 60mm side by side out front of Kent's Sports in Ogden looking at Mt. Lewis. WOW is all I can say. I spent about 30 minutes comparing them. Here's the run down. If I rate the Swarovski the highest at 100% the vortex was right there at about 95%, and the Nikon about 60%. I can easily settle for a 95% scope for $429 vs Swaros $2200. I'm going back with the credit card. And the unconditional unlimited warranty, holy cow. Quoted straight from their borchure "Vortex will repair or replace the porduct absolutely free - no matter the casue!" You guys need to check these out. Looked through the Razors as well, amazing for the price.
