I just bought a Dickinson 28 ga. Actually, my wife bought it for my 50th birthday. (She’s a keeper!) Seems real nice for the money. Only complaint I have is the triggers seem a little heavy. Good value. We are still in the grip of winter here and I haven’t shot it yet.

I think the old SKBs (Japan) were good and new ones are made in the same factory as the Dickinsons. Some nice used Spanish and Italian guns as well.
triggers on your 28 should lighten up with use.
