Until they run out, the best deal IMO is the 243 and 7-08 Marlin XS7 at CDNN. $280 gets you an accurate rifle that doesn't feel cheap like the Axis or Ruger American. If you want to get up into the $500+ range, then definitely Tikka or Ruger Hawkeye.
That's in new rifles. I agree most of the best deals are found in the used racks.
