Old thread but still a valid topic. Where out of the box accuracy is the top priority, I lean toward CZ's and the Savage Mark II's. The Savage rifles are cheaper. That said, you can do real well with the basic Marlin Model 60. The ammunition choice is probably more important for consistent groups along with either being very comfortable with your trigger or improving the trigger.
The budget is the problem as everyone wants the most accurate 22 rifle they can lay their hands on. Tis why I moved to CZ's, the better Remington's, Weatherby, and Anshutz grade of rifles. My Savage Mark II American is actually an excellent shooter but it was no $150 rifle when it was new. If you want to use iron sights, the CZ 452/455 Trainer is a good choice and cost effective.
