Just bought the 15-30 model a month ago. For a compact, I gotta say that scope is very nice. Sure, it's not a big Vortex, Leica, etc., but for the money it's a solid scope. Looked at the compact Nikon, but it was quite a bit more. I plan on using mine strictly as a small quality scope to keep in my pack to use on hunts (going as light as possible). Would not take a bigger model because of weight. Honestly, the 15-30 model is small and very light...plus it gives you a little more reach over the 10-20 model.
