Well, after my experience with Vortex and their customer service...I am a fan for life and would choose them over anything else. If I had not found the Celestron at such a good price, I would have gotten the Vortex Viper.I'm looking at Vortex Viper HD and Pentax PF-80ED-A myself. Leupold SX-4 Pro Guide is on the list also.
My Vortex Ranger range finder died on me after it's second time being used...gave Vortex a call and no problemo, they overnighted me a new one with a return shipping label to send the old one back. Can't beat that type of warranty!
