Personally have an old uggie 20.gauge Double. Not a real well known gun (real enthusiasts know them) but I love it. One of those guns that just seems to float to your shoulder and follows target easily. I shoot it better than any gun I've owned. Not the cheapest, but you might find one in your price range. Check em out online.
Actual name is Ugartachea but commonly referred to as Uggies. You'll find info online under uggies.
The Weatherby Orion is not bad, I picked one up this spring. Sportsmans Wearhouse has them for under 1K. They are made in Turkey with Weatherby's design, warranty is handled by Briley in Texas. https://weatherby.com/store/orion-sxs/
