SIG Kilo2000 is the best for the money. Don't even bother with the 2200 or the 2400, more bells and whistles, but no more range. There are better rangefinders at the $2K+ price point, but this one will get you what you need. Seen them as low as $350, usually between that and $400. A tripod mount is helpful once you get out past about 800. The Vortex is about the same price, but maybe 60% of the range, just for comparison.
I have ranged elk at 1400 and steel plates a tad further. It is what I use for hunting and precision rifle matches.
Burris does not make a rangefinder anymore. Bushnell makes the 1 mile ARC, the SIG is better and about half the price.
