My answer to your question ... the "best" will be a top end scope. Something like a 1.5-6, 42 mm , 30 mm tube. These will set you back $1500 to $2000 or so. On a moderate budget? Look at the Zeiss Conquest. It is about $550-$650 and a great buy. For what you look like you are wanting to spend, don't leave out Pentax, Leupold, Nikon or Burris scopes in that price range.
