CZ's O/U and SxS are made by Huglu in Turkey. As stated, look, fit, finish, and wood quality are all excellent. Quite frankly, I would not hesitate to put it on the rack next to any gun costing under $3000.
I too have a Woodcock (20ga) with about 250-300 rounds through it with no trouble. It is slightly longer, which I like as well, and the trigger is probably going to get some work done after about 1000 rounds.
Some folks have had mixed luck with durability, and I agree the jury is still out. That being said, CZ has an excellent customer service reputation and I would buy another one at this point.
DeHaan is another importer of Huglu shotguns. He specifically advertises the availablity of left handed stocks, so I'm guessing there is some difference. Check out his website for more info
