I agree with the above poster. You are asking a lot for not much money. I was going to suggest a Zeiss Conquest 6.5-20 with mil dots, but most stores won't even let you look at one if you only have $350 in your pocket.

I am not really into cheap optics, but surely Bushnell, Simmons, or Tasco makes something to fit in your price range.

Good luck.
