Used?
Good luck in your search. Your parameters - SXS, under $200, not junk - are for the most part mutually exclusive.
The best deal that I have seen on a used SXS in the last couple of years was a Savage 311 SXS for $265 in Dugan's gun shop in Hughesville, PA. It was there for years, might still be - tight, bright bores, bomb-proof, camo, heavy. That is the least expensive SXS I've seen. Why no one wanted it, I can't say.
