Find a Vintager group near you. They'll have access to lots of SxS of all makes. I have yet to meet a Vintager that wouldn't let you try a few shots (with his ammo).
Guns to consider if you don't reload and will be shooting off the shelf ammo.
As Stan said, BSS (skip the sidelock, too much money)
Ruger SxS
CSmC RBL 12 in clays configuration (too heavy for me, but an excellent choice)
AYA's in boxlock or sidelock. They are modern guns built to English standards.
Winchester 21s, in a not collectable configuration (reblued, etc)

PS to Stan (I look forward to seeing you at the Southern!)
PPSS (I will win, you pick the event. We shoot together. I'll wager cheap/cold beer)).
