Of course you should get what you feel like, but you have a 9mm you love so I'd encourage you to get the .22. It will give you some variety in your shooting time and OMG yes it's cheaper to shoot! Like almost everybody I have to think a bit about the cost of ammo when I shoot my 9 but with the .22 it's not a factor unless I'm wanting to shoot some serious match-grade stuff. Which is not very often. Lots more practice time and plinking fun. I have a Smith & Wesson 22A and a Ruger Mk III and love shooting them as much as I like shooting my Glock 19. Good luck whatever you decide and congratulations on the Beretta.
