I bought a "cheap" one from Amazon and it has performed brilliantly. It also has the added benefit of taking regular AAA batteries which are easy to keep in the bag for emergency battery changes. It is a YUNDOO brand, but I'm not sure if it still available. I'm sure any cheap chinese rangefinder would most likely be the same exact thing, made in the same factory. Don't have any qualms about getting a cheap one from Amazon. It even has the slope feature (which I don't ever use). It came with a nice little carrying case as well.
