You've got many choices but "best" is up to your eyes to decide. I'd recommend checking out ones such as:
1). Vortex Diamondback 8 X 42 - $200 approx.
2). Bushnell Excursion 8 X 42 - $155 approx.
3). Nikon Trailblazer 8 X 42 $150 approx.
4). Pentax DCF HS 8 X 36- $175 approx.
5). Sightron Big Sky 8 X 42- $250 approx.

The Sightron is a little over budget but they have good glass. I'd probably go with the Vortex or Pentax if it were my choice. Good luck on your selection.
