I'd recommend looking for a used Marlin in the 900 series as the 900 series has a trigger upgrade over the previous 700 and 800 series rifles.
All of the newer Marlin rimfires that I've owned in 17HM2, 17HMR, .22LR, AND .22MAG have all been good shooters. The Marlins are also a little larger than the comparable Savage 93 and 93R17 series rifles, more "man sized", if that makes a difference to you.
My experience with Ruger American rimfires has been, to say the least, disappointing.
