I picked up a used Weaver 6x24 at a local gun show a few months back
for $160 and it seems ok so far at 100yards. Not as sharp as some better scopes but fine for the money. But if you have $600 to spend you might be able to get a Bushnell Elite which is really nice, or check out a new Weaver or Vortex. Used Luepold's are also a good by as they are guaranteed for life I think. My older Luepold Vari X III 6.5x20 is as sharp as anything I have had since. I think for 200 yards you probably need at least 18x on the high end
For target work.
