I hate to rain on your parade - but I think they're made in Turkey too. I just can't tell you they're a good long term gun but they are inexpensive.
You have the Benelli Super Sport 20ga - which would be fine / and you know I like it, but it isn't a "wow" gun. A good O/U in 20 or 28ga are certainly good guns - and you know I like the Browning XS Skeet - you may find a good used 20ga for about $ 2,000 - but new they're about $ 2,750 out here. There are some 28ga in the XS Skeet model around. But I've told you before I think that model in a 20 or 28ga with 30" barrels is a very good buy ( but easy for me to say, I already have them ..).
If you really have your heart set on a SXS - Cole Gunsmithing is a big Beretta, Zoli, etc dealer and he might have something used - but I think you're still in the $3K - $5K range for a wow gun / and don't forget most of those guns are short, with small pistol grips - and they have a lot of drop at comb and heel. Putting an ugly stick on pad to raise the comb - is going to take away from the "wow" factor a little...
If you have a good gun dealer in your area - they always seem to have some pretty good looking SXS's in stock - maybe an AH Fox ( under $3K ) or something.
I think a 28ga, if you think its enough gun, is really your best bet. Browning, Beretta, Zoli, etc all make 28ga's - and operations like Cole make up multiple barrel sets ( where you can get a Beretta receiver and 2 sets of barrels one in 20ga one in 28ga ) but you're back in that $3K plus area again.
A Krieghoff K-20 would be a " wow " gun .....
Another gun out there getting a lot of good press is Blaser - there are a number of big dealers around the country that have the F3's in stock with a full set of Briely tubes in them ( for 20, 28 and .410 ) - but I think most of them are $ 8K - $ 12K probably.
Hal Dupont is a big dealer in Florida - he might have something he took as a tradein / or something he didn't want that he knows somebody is selling.
http://www.halkguns.com/ A friend of mine knows him real well - and speaks very highly of Hal - I think he sells Krieghoff and Kolar - both real nice guns. A lot of his inventory is $ 20K plus - but talk to him and see what he has / besides its fun to look.
