I won't bother replying because it will just mimic what the members above me have said in regards to the Elites
IronWorker, the 6500 has the same glass as the 4200's does it not? I've heard nothing to say otherwise. You have both, what do your eyes see?
zjfty9, end the pain and order the damn 6-24x50

You won't regret it. If you do most of your shooting to 6 or 700 yds, you won't need the 20moa base but no harm in getting one for those "just in case" moments. End the misery and order it.
The Optic Zone and Bruno's Shooter Supply are the only 2 I deal with. If one doesn't have what I need, the other gets called upon. Bruno's didn't have an Elite 3200 10x my cousin wanted, actually their distributor showed no longer available so it's not their fault so I checked availability with Optics Zone and they had 1, needless to say it's on the way. Amy @ Bruno's & Jon & Tammi @ The Optic Zone are all top notch people to deal with. It makes spending those big bucks so much easier.
Did I mention you should just go ahead and order? Let us know what you decided on! adios
