If you can pick up an used Leica Im sure you'd be happy. If new and looking for a decent unit Id go with a Bushnell Elite 1500 or Yardage Pro Legend.
If I were shopping for one Id want one that can range a deer out to 400 yards if not farther, probably would never shoot one that far but it would be nice to know.
From the chatter on the forums I would stay way clear of the Leupolds, from what Ive read guys are having problems w/ them.
Cheers!!
