RE: Brunton vs. Pentax
I just purchased ny second paur of Brunton 10x42s, not that I had any trouble with mine, my wife took over my first pair, for the money they are great. I also have a buddy that loves his also. Im like MOTurkeyTamer in that I have no experience with the Pentax so I cant compare them, They are probably both quality optics. If possible try to get a pair that are FULLY-MULTI-COATED. That means that every lense surface inside has multiple coating layers. The Bruntons are but I dont know about the Pentax.
