Billy,
I own a 3200 and several nikon scopes. The 3200 and the Buckmaster are similar in terms of marketing - meaning that the 3200 competes with the Buckmaster, and the 4200 competes with the Monarch.
Between the 3200 and the Buckmaster, I would, and have, pick the 3200 - WITH NO HESITATION.
As for the Rifleman, to me it sounds like a poor man's Leupold. To me, the Rifleman doesn't even compete with the 3200 and Buckmaster. I think that the Leupold VX-II would be in the same class as the 3200 and Buckmaster.
