If you want a semi-auto, a 10/22 is a great gun. Might want to look for one used, though, and get it for less. Shoot it with the factory barrel (the accuracy isn't as bad as many say, but it ain't the greatest, either, and $100 gets you a nice Green Mountain bull barrel, which is a very good barrel). If it satisfies you, great...if not, it can easily be improved...
You might also get some trigger work done or replace the hammer with a target hammer if you desire, and replace the magazine release with an extended mag release. One of the great things about the 10/22 is the wide availability of aftermarket parts and accessories. Just about everything is doable by you easily, and you won't really need more than some screwdrivers and allen wrenches for the barrel...
Mags are widely available, too, and for decent prices. Can't really say the same thing about most of the other .22s on the market. Stick with Tactical Innovations, Butler Creek, or factory mags. get the Butler Creek speedloader, too...
Have fun, and remember, whether you run it stock or change everything out to make it a $1000 gun, they are very fun...
