Lloyd, there's one that I forgot to mention, the Valmet. Same lockup at the Kreighoffs and Remingtons. There have been many of them made and sold, they were also in production under the name Tikka, and now, apparently, Marocchi. Machine made guns, but held to such close tolerances that barrels will often interchange with no need for fitting. I owned and shot a 412ST for years (32" barreled), but they're readily available in other barrel lengths. Very, very tough guns. My friend Charlie Boswell, who developed and founded the CompNChoke line of choke tubes shoots one exclusively at clays. He owns a Kreighoff, has owned a Perazzi, in fact just about every target O/U in existence. But, he shoots the Valmet better than any of them.
Evidently, a Marocchi 612 can be ordered with double triggers at the list price of $1500. I can't speak for the quality of the Marocchi, but the design is unquestionable in durability.
