I've been running Geovids for several years now and absolutely love em! They're pricey, but no worse than buying a top of the line binocular and a separate rangefinder (Leica, Zeiss, Swarovski). You'll hear guys say they're heavy, but again, no heavier than a good quality binocular and a separate rangefinder combined. The convenience of having both combined into one unit is priceless to me.
When you get ready to buy, contact Doug @ Cameraland. He's a board sponsor and a great guy to deal with. They also sometimes have great deals on demo Geovids.
