I got a Nikon 600 off E-bay(new, saved about $90). So far I love it. 1/2 yard accuracy out to 100yards. I pulled the tape measure out and placed objects at various distances and it is on the button. I play around with it all the time at to test capabilities and it works great in pretty nasty weather. Here in Upper Michigan where I live, we get some nasty weather and I am lucky enough to have a pretty tame deer herd in town. There is a city park where I have gone and ranged deer in heavy snow fall and it works great. The Nikon is awsome. It has made readings out past 700yards while ice fishing(large objects AKA houses). As far as size and pocketability goes, can't get them much smaller.
