While its above your price range, I would consider a Leupold with 12 power and their Target dot.
Oddly, the Target dot is not that expensive as an selection.
More or less you either get a good deal on a 12 power or better Leupold or order one from the factory as a Target/ larger dot (I am partial to small dots) . A few bucks more than the standard reticles as you sort of get credit for not having one.
Other option is a used one or a great deal and sending it in. They only do Leupold so the Redfield is out.
something you want to check out as they have other dots and I do not shoot varmints (there aren't any to shoot up here, politicians are exempt unfortunately )
I got to shoot a Target type dot a few weeks ago and its the reticle for me, I dont' do well with fine crosses but the dot was perfect.
