I've been researching them and I've narrowed it down to the Vortex Ranger. The optics are very clear and the red display shows really nice. The Leupold was a little faster to read distances but the Vortex is waterproof and comes with a lifetime warranty. I didn't find any other brand that offered a warranty like that.
I own a Redfield 550....a simple, no frills and very compact device. Found that accurate out to 200yds ..... if memory serves, I got that last year for $160 all inclusive from Cabelas.
