And, if you take that $ you saved from buying a Sport, you could buy yourself a 15/22 also, which you'll enjoy ever bit as much, but won't be throwing $15 per mag downrange every time you go to the range.
The easiest way to stop throwing $15 downrange with eacg magazine is to shoot 10 - round magazines at the range!
Or find cheaper ammo

I am not sure about where you are but its about $7 for 20 here.
