If you are talking about new or recently-manufactured used without a doubt Ugartechea is your best bet.
The Uggie Model 30 that Lion Country sells is a good value, even with the weak dollar. The used Uggies out there, either sold by them or under a variety of importer names, are real steals. I picked up a Excel model 221 (really, a Uggie model 30 with some cosmetic differences) in the classic English game gun configuration for $500 a few years ago. The craftsmanship in those guns is far above what you see in the recent Turkish imports.
Keep in mind that your dollar doesn't go as far with a SxS as it does with a O/U; the SxS market just isn't as big here in the US and there isn't the "economy of scale" like there is with O/Us.
Other options would be a used SKB; you could get one close to mint condition at $1500. The Fabarms guns imported a few years ago were pretty nice but a bit heavy for an true upland gun IMO. You could also get a Browning BSS or maybe a Beretta GR-3 or older Silver Hawk in that price range assuming you are looking for a 12 gauge.
