Jeff,
I bought the same type Ruger 10/22 you are looking at, and I bought it at Walmart also.
It's my second 10/22 style .22 (my first was an AMT 25/22, all stainless including receiver, with folding polymer stock). It was stolen when my parents house was broken into along with many other nifty guns.
The Rugers are THE way to go aas far as .22 rimfire. You can send them off to people like
www.gunsmoke.com and trick them out or keep them the way they are and they are still very useful/fun.
