Got one. Bought it new. Was very disappointed when Remington discontinued it.
It's a great shotgun. The only problem I have had was a worn rubber piece in the top of the receiver was causing issues, but Remington fixed that for me (when it came back it went from NY to STL via Ogden UT, but that's UPS's problem
). It's soft shooting, points well, and I shoot clay targets with it like it's got a radar tracking system.
It's more intended as a field gun than a clays gun; it's tuned for heavier loads, so if you're thinking about lighter loads it might not be ideal (it works ok with 1 ounce loads, but 7/8 is too light to cycle it properly).
Make sure that the one you're looking at is a "II" model (it's marked on the receiver); those have far fewer feeding issues than the original version. Remington was fixing the originals to "II" specs, and I see no reason why they still wouldn't.
I will say Big Green has treated me well with it. I broke the charging handle (it's kind of flimsy) on it (was hammering on it to open the chamber after trying to run a bad reload... my mistake). When I called them to buy a new one, I learned they had none in stock and they weren't sure what to do about it. I ended up posting on Remington's Facebook page (of all places) about it, and the funny thing is that the customer service department jumped on it, and they made a run of the parts (if I needed one, I probably wasn't the only one, and if you make one, you may as well make a bunch). Seeing as how they abandoned what was to be their flagship shotgun after a very short run, I was impressed with their service.
I like mine, but it's still an orphaned gun. There's no way I'd pay over $900 for one, and $800 sounds a lot better. IMO, had they kept with it and introduced models tuned for lighter loads and clay shooting, it might have done better. It's not a bad design (very closely related to an Ithaca 37, but rigged to run as a gas-op autoloader), but it was tricky to get right.
