I would try to save a little more money and buy a Leupold rifleman series 3x9x40. This would be my first choice on a budget. Second try Burris or Weaver.
here is the link for the Rifleman scope:

One more thing I would reconsider a 50mm objective lens. I made that mistake on my first hunting rifle. Now I go no bigger than 40mm-44mm on a big game rifle. 50mm-60mm on varmit guns is ok tough. Just my opinion and 2 cents.
Aim Straight,
