Good choice in the inexpensive group for 2-7s or 3X9s. The Sightron S1 is another solid choice - along with the Millet Buck Gold & Bushnell Legend/Trophy. All of these are similar prices & you cannot go wrong with any of these choices. How I rate them...
Sightron S1
Nikon Prostaff
Millet Buck Gold
Bushnell Legend/Trophy
Should you find a few more dollars under your dresser, move up to the Nikon Monarch, Sightron SII, Bushnell Elite.... lastly the Simmons Aetec... but's it's long & heavy - not suited for everyone using a ML.
Just my 2 cents.... my eyeballs!
