Marlin model 60's:
I have a couple of these and a few other Marlins in my collection. They are "good" guns, and tend to be very accurate if kept clean(barrels) but they have their problems.
They can be very finicky as far as ammo is concerned, even for 2 identical guns. some run them "wet" with quite a bit of oil lube, others(including myself now) use dry graphite for lube. The 14 or so round feeding tube is handy while hunting for good ammo capacity and no mag hanging off the bottom of the gun, but takes a while to reload. Not much aftermarket for barrels, just a couple stocks and that's about it. Not drilled or tapped for scope mounts that I know of, just the 3/8" dovetail scope rail.
I don't think you would be happy with one for your "Appleseed" gun.
I know nothing about the new S&W or Colt AR22's that just came out. I use a Ceiner 22 kit in an old 1/12 twist M16 barreled upper on one of my AR's, it's fun for plinking, but I have never shot it for accuracy.
That leaves you with the 10/22. How much do you want to spend? $200 to $2000 is easy to do.
If I make it to an Appleseed shoot(like I want to), I'll be using either a Marlin model 80DL bolt action(with 7 round mag) or my model 81DL(with tube-feed mag). Both came from the factory with a 23" barrel, peep sights and are early 1950's vintage. They are pretty darn accurate.
