Are you talking about .22LR or .22 Winchester Magnum (.22WMR)? Your designation is a bit confusing. Marlin has several offering in both calibers that are bolt action's with tubular magazines.
Marlin doesn't make their .22 Mag in semi-auto any more.
I've had more Marlin bolt actions than any other brand. The fit and finish is just nicer than what you get on other guns in the same price range or less. It's not to say that the others won't shoot though. I've had several Savage's in .22, .22WMR, and .17HMR and they all shot extremely well.
For less than $500, it's almost impossible to beat the CZ line of bolt action rimfire rifles. Fit, finish, and performance are OUTSTANDING.
I've shot a couple of Ruger 77/22's in LR and WMR too, and they were really nice.
If you like lever actions, the Henry line of rimfires is pretty sweet too. I've only shot the base model ($250 or so) but it is a tack driver.
