PLENTY of Euro O scale model trains made. Just open the wallet WIDE!! MTH locos and cars are on par price wise with Lionel. And as stated already there are Euro manufactures but they make the MTH stuff look cheap! (why MTH entered the market) Looking for cheap Euro trains is tough. But I find LIMA brand O scale Euro trains on ebay from time to time....but they often go for more than I am willing to spend.
EZ to find......but it takes $$$$$
