100 rounds for $12 isn't bad.
For a beginner, though, that Ruger 22 is just a great pistol for learning to shoot. It's accurate to a fault. Any in the line of Mark II or III with a bull barrel is a great buy.
Yeah, I still shoot my MKII all the time, fun gun.
But if you are thinking about buying a Ruger Mark II or III, go with the MKII.
You will come to hate the LCI on the MKIII. It's a B!#*% to clean.
