Until you find your dream gun, you can have fun with a Model 24 Stevens/Savage, the classic US made .410/.22 o/u. Later 20 ga/cf rifle versions are downright ugly, but the originals have nice lines and come up easy. Mine has a post-WWII Tenite stock -- an innovation 30 years ahead of its time -- but Ive seen them restocked in nice wood for a classy looking walking-around piece. They don't have the panache of a fine doublegun, but IMO they're the factory-made US version of a rook-and-rabbit rifle, entirely serviceable around the farm and in the woods.
