Yeah, SKB 505 or 585 O/U. Maybe a hair more than a grand. A real favorite in 20.
I wouldn't buy any autoloader for skeet and SC, if I had a grand. Semis are a PITA unless you have servants, and if you really shoot you will reload. You will be glad you have an O/U and you will regret using your grand to get a semiauto. Cleaning is a lot easier with an O/U, retrieving hulls is a LOT easier, it's safer at the range, and you can be ready to go with 2 in the chambers, rather than having one in the chamber then having to quickly load your second shot when it's your turn.
And I'm with kentucky_smith. I have a very old 1100 Magnum that I picked up cheap and works well, but it was never worth a grand and the new ones REALLY aren't. And I don't use the thing much at this point, and when I do, it's for hunting, not the range.
If you MUST get a semi, get the 391 Urika. But don't get a semi.
