Gun stores usually carry new and used firearms. If I were to have either a 22 or a 12ga, I'd rather have the 12ga first. Shots with a 22 on small game are usually within shotgun range anyways.

IMO Winchester makes the smoothest shooting pump gun around, followed by Remington and Mossberg. Sorry Benelli guys, never did care for how the Nova felt
