Leica are definitely among the best in my opinion. Little more expensive than some, but quality & clarity that will outlast the others. Well worth the investment!
I've had my Leica Geovid binos w/built in rangefinder for about 15 years so far, still as good as the day I bought them. Also nice to have all in 1 unit, as opposed to having to lug around 2 items (binos & a rangefinder). The red lit display is the easiest to see & read in any lighting conditions, unlike others with black display which are difficult to read in low light.
I have a backup Nikon rangefinder, but rarely use because they are inferior in every way imaginable.. (poor display in low light, less accurate, less light gathering, less clarity)
Friend of mine found a used Leica 1200? handheld LRF on fleabay last spring for $300-$350, there are some affordable deals out there if you are patient.
