10/22 you can get used one for less than 200 bucks, new for not much more, the only gun they make more after market stuff for is the AR platform...It is the best .22 out there.....I like the Marlin 60 too, and can't go wrong with a Savage 93...but IMHO 10/22 is the s&%t!!!
If you are walking through the woods squirrel hunting with an AR look alike you may get more attention than you want.
LOVE my 10/22 and my S&W M&P 15-22 bought the Ruger new and the M&P used. They cost about the same since I found good deals. Probably the best money ive spent so far on firearms. Cheap, fun, reliable, accurate. Just great!
