I don't own an SxS shotgun (I WANT ONE THOUGH!), but I own an O/U shotgun and shopping for either one can be a pain in the ass. For some reason cheap pump actions seem to work work work yet, a cheap O/U or SxS may leave you disappointed at the range or in the field. I purchased a CZ Redhead and I’m super happy with it. I've had it for about a year now and got 12 grouse with it last fall hunting season. I can't stand the American style round knob pistol grip but for the quality it is I was willing to settle. I looked at a CZ Bobwhite at Wholesale Sports the day I got the Redhead and it’s a nice quality piece. CZ Shotguns are made by Huglu, A Turkish Company. An American high class shotgun brand Deehan also have their shotguns made by Huglu just they do the engraving themselves and sell it for $2500 with only two years of warranty well CZ sells them for $800 with 5 years of warranty.
If you can't afford the $800+ for the Bobwhite then get a Baikal. Them crazy Rusky shotguns are built like the AK-47. Super ugly, cheap, and they just work work work. The Savage Stevens SxS, if they even make them anymore, are alright shotguns.
Stoeger got a bad rep years ago when the IGA shotguns were really poor but, Beretta took over and the company is putting out some decent shotguns (just ugly) now. Their coach guns are very popular.
The pieces of crap you want to stay clear away from are the Mossberg Silver Receiver SxS and O/Us. Everyone I know who got one loved it at first, then months later the firing pins break and they hated it.
