I have a Leupold 12-40 60mm that I've had forever, and that's what I use most of the time, since it is my only scope. It is not the best optical quality (non-HD version), but good enough for a lot of uses, reasonably compact, and free.
I borrowed a Vortex Razor HD 11-33X50, and it is a sweetheart of a little scope. Great quality, and the zoom range is well matched to the optics, so you don't end up with magnification that is useless. On the other hand, while using it I was wishing for the X's in my leupold. It just didn't have the reach at 33 power to do what I wanted (distinguish if a ram was full curl at a couple miles).
I am shopping for a 65mm Leica, just have trouble spending the money...
