A guy at work turned to me for suppressor advise. I have no interest interest in them and never read up or studied them so I said I'd ask around.

This guy is not a gun guy. He's not going to be training or doing drills. Probably not even going to be shooting it a lot. It's just something for occasional fun. It would be going on a Ruger 10/22 .22lr

Price range max $400

The local gun store has the following...
Yankee Hill
GemTech
Ruger
