Honestly, a 10/22 is a LOT of fun.
If you really want to learn to shoot well, I would recomend not buying one.
They are so easy to rapid fire that they do not really reward good technique.
If you want to learn to shoot a .22 rifle well, get a bolt action, lever action, pump action or single shot. Personally, I think lever and pump guns are the coolest.
The point is to require a slight bit of effort for each shot - psychologically, this makes you "value" each pull of the trigger enough to want to do it right.
But thats just my opinion - a 10/22 is a great gun and you will have a lot of fun with it - but if I had one, I would probably go find some of the 30 round banana clips...
