Lots of choices: Winchester 21 & 23, Kemen, SKB 385 & 485 plus new batch from Turkye, AyA 56, Arrieta 600, ..... Even Merkel made heavier one with choke tubes for sport shooting. I would say the best value would be Sears Roebuck 100 made by Aguirre & Arranzabal.
The best bang for buck would be ca. 1980 "verticallelas" from Brescia by Perazzi. The ones with fixed trigger coil springs and no rib between barrels are true bargains. I have seen one in excellent condition w/o original plastic hard care and accessories for about $500 more than typical BSS 12 ga Sporter in same condition. The Italian gun has superior trigger, barrels, choke tubes, Boss-type barrel/receiver locking system that will last hundreds of thousands rounds.
