The AYA No.56 is a fine choice. I had one that I absolutely loved.... just couldn't hit much with it.
AYA is now offering a hammer gun as well. However, I am not sure of the price (close to $20K I believe). Here are photos of one ordered by a member of the "Spanish Gun" forum at Shotgunworld.
If you willing to settle for something a little less fancy and a little less costly, I am selling a nice modern Beretta MI-VAL pictured below. It would make a great clays gun.
