I recently bought a used Burris Timberline 4.5-14x32. It's rated down to 7 yards but I think it will do a bit better than that. I can try it next time I'm home.
It's in your budget if you can find one. No idea how it compares to the Leupold that Yo suggested.
However, if fast target acquisition is needed at 10' you might like the 2-7x32 or 3-9x32 versions better. I assume they have the same 7 yard parallax as the 4.5-14. They seem to be harder to find than the 4.5-14, however.
I'm not a fan of either the Bugbuster or Hawke Vantage but agree the Hawke is the better scope. The Bugbuster focuses better at close range, however and I do prefer the side adjustment versus the objective adjustment of the Hawke.
