I'm reviewing one of these for the next issue of the mag at the moment, and killed a deer yesterday with it at 520 yards. I have to say that the new Eliminator III is streets ahead of the original. The optics are way better, it has an adjustable objective, the reticle doesn't have anywhere near as much target obscuring wiring on the edges, and it works on any magnification. The 4-16x is also a much better power range for long range work. It is certainly fast to get into operation, and the ranging button is actually in a good position in my opinion to use with your left hand. The old remote always went flat when you needed it most, so I don't think its a bad thing they've canned it.
I'll never change from dial up scopes personally, but as a quick way for someone to get into long range, these are pretty amazing.
