I have a Revic BR4, Leica Geovid Pro laser range finding binoculars, and an Sig Kilo 2000 LRF (no ballistics). I previously had a Leupold TBR-1000 which I gave to my brother in law. I've also used the Gunwerks/Revic original BR2's, Kestrels with Hornady 4DOF, and the Revic BLR10b laser range finders at courses.
LRF is mature technology IF you do not need ballistics. Pick one at the price you can afford with the warranty you want. Any of the ones I've used worked well out farther than I shoot.
IF you want ballistics, and they fit your budget, I highly recommend the Revic BR4 or BLR10b. I think they are the easiest to use laser range finder with ballistics of those I've used. My Leicas binos have Applied Ballistics Elite ballistic calculator which is also good but not as easy to use IMO. I also really like the ability to switch from near/far ranging mode on the Revic's.
The lifetime warranty is excellent on those companies that have it. Like most things, if they don't die in the first year they seem to last a long time. My Nikon Laserforce range finding binos but the dust after one season.
