Used to be, when our Wal-Marts in this area sold guns, you could go in and buy any of the H&R single shotguns for $89.99. I never did buy one back then but I have a H&R Ultra Slug now and love it.
As to 16s, I don't currently own one but I want to get one soon. My FIL used to have a Stevens SxS 16 and I loved that gun. He traded it for another gun. Used to love that gun for rabbit.
