My advice for what I would buy RIGHT NOW, is a Zeiss Conquest 3-9x40 with the Z600 reticle.
With mail in rebate they are $379 and that's a hell of a deal. It's what I bought a few weeks ago. Mounted it to my rifle and it is easily the nicest scope I've had the chance to look through. If that's a little too rich for your blood the Nikon Prostaff line for under $200 is a great value.
A lesser known brand I would also recommend you look at is Sightron. Their Big Sky line has rebates right now and is a little less expensive than the Zeiss right now I believe.
Check them out.
