A more "moderately" priced sidelock over/under shotgun is the Merkel 303 series, a wonderful gun in it's own right. Other companies have "cloned" that design (AyA, Ugartechea just as examples) so patent rights may be gone. May not be in the same class as a Woodward/Purdey, but it's an excellent design and highly prized by those that own them.
