I, too, love my Kadet kit. It is great for practicing, very accurate, and generally cool. I, however, am NOT selling my Ruger Mark 2 Target 10", yet. The tricked out 10/22s are cool, too. But, for the price a good bolt gun will outshoot 98% of the 10/22s, IMHO. However, you can make a 10/22 more accurate, but you can't make a bolt gun semi-auto. I was looking at the CZ rimfires when I ran across a good deal on my Savage/Anschutz Mark 12.
Now I'm wrestling between a CZ 527 in .223 or CZ 550 in .308. I'm a plinker, so .22s are the general rule, but I want a "big" gun in .223 or .308.
Cheers,
