I have a halo range finder and I haven't had much trouble with it, I think it was $120 new a couple years back. I've had the same battery in it since last fall and it is still going strong, although the year before it ate a battery in less than a month. On the long range reads it sometimes has trouble picking up distance or takes a long time. (We're talking 170+ meters though). I use mine primarily for bow hunting and in that arena I have no complaints, but if I was going to use it for longer ranges I might invest in a little better quality one.
