Need suggestions on scope replacement

[mkg]

Hello all,

I have two Weaver Gram Slam 6-20X40 AO/DLPV scopes that I am very happy with . However my eyes are getting older and reading the numbers on the turrets is becoming increasingly harder. I am looking at replacing them with a tactical / target turret scope ( I have looked for replacement dials and they are not available ) .
Right now I am looking at ...
1). Bushnell 4200 elite tactical 6-24X50
2). Hawke Optic frontier 6-24X50
3). Maybe Zeiss Conquest ( upper limit )
The big problem is that there is nowhere locally that I can look at these scopes. So, I need to rely on all of you for help.
Generally these scopes get used for varmint/predator , and whitetail hunting plus offseason target use out to a 1000 yds ( want to work out further for targets )
So any info you can offer would be a great help.

Mike
