Of all the rimfire rifles and hanguns I've ever owned, Ruger stands out as the most versatile, economical, and probably best built for the money of anything out there. Once you get into it, you'll want to modify the gun in some fashion, just to make it "your own", so to speak, and there are tons of after market parts for these guns. .22 ammo is cheap, quite accurate and not extremely loud, but I still use ear plugs. Yes you can buy sub sonic ammo, but I've very often had issues with various guns using it...semi-autos won't cycle it, I've always used a revolver, and it is a good bit quieter than .22LR....just don't expect any outstanding accuracy.
