As far as scope the elite 3200 has been a great scope for me for the investment. I wouldn't ever consider a leupold rifleman. Nor would i choose aVXI over3200 or nikon, or burris...you get the idea. I have leupolds Varix III, VXIII and M6 still...the old ones I felt were worth it then but the new ones in todays market and better choices..not so much. Well at least the variable power models.
I have an elite 3200 on my knight, my other 2 inlines wear zeiss conquests. Not sure what your looking to spend but if its upto 400 I suggest the 3x9x40 Zeiss Conquest, a truly great scopein this price range/class. If this is more then you have in your mind the 3200 elite, Nikon Monarch, Burris FFII, etc will work. Take a look around for any 4200's, i have heard of great deals on this scope as of late it maybe getting phased out now that the new 6500 is out. Not sure but a guy I knowpicked one up for 50 bucks more then the 3200, a steal.I use to have one of these as well, excellent scope very good low light performer.
As far as power I guess a lot depends on your eye sight but I have never needed more then 10xin a big game hunting scope.
Forgot to mention don't buy without trying a number first. Optics are like shoes not all fit the same you must try them to find the one that fits!
Best of luck
