The Leicas will give the best optical qualityand are overall my favorites. The CRF Rangemaster 900
is a bit less than the 1200. The Swarovski Laser Guide
is also excellent but a bit bigger and more expensive, but has a longer maximum range than the Leicas. Besides these two standouts, everything else is similar in picture quality. I use a Nikon
1200 which is a great unit, but does not have the optical quality you seem to want. A laser rangefinder
gives distance, and since it is not a unit that will be looked through for any amount of glassing, optics are secondary.
