I've owned one for two years now, have (at least) a couple thousand shells through it and love it. Mine's a lefty, synthetic model, which is why I bought it for clays and ducks. At first it didn't like light loads, although a little shooting smoothed it out. It takes the Light Game Loads every time now, but still has the occasional FTE on AA Light Trap Loads. Easiest autoloader to clean, just takes a light spray of CLP and some swabs, and I'm continually amazed at the quality to price ratio.
SIG was going to be the distributor, but things fell apart, and allegedly Tristar is picking up the line. Their website doesn't mention that, though.
All said, I would pick up that Fabarm because they're great guns, they're selling out fast, and you will not regret the buy. Look at all the crap you can buy for that kind of money. Besides, H&K will still honor the warranty on Fabarm guns sold under their name. What more could you ask?
