Well I ended up ordering the 20 gauge Tamer from Wally World. It was $188 plus tax, which seemed a little high to me, but it's what I kinda wanted.
Of course I went in a pawn shop the next day and they have a 20 gauge youth model with synthetic stock for $80 OTD. It's not in the greatest of shape, especially since it's not that old (NW serial number). But that is perfect for what I'm looking for.
What I wished they made was a Tamer without the nickel finish. I realize that the youth model is only 2 inches longer, but I would prefer it to be 18 inches really. It is nice that it has the modified choke. I'd like for my 9 year old to be able to dove hunt with it, but the barrel weight is what I think will cause him the most problems.
Oh well, I guess I should just go back and get the youth model just in case.
