I ride a Surly CrossCheck and I love it. To tell you the truth, I was kinda bummed when I learned that they're made in Taiwan. But then again, it was kind of foolish to believe that anyone in the US would be making a nice steel frame and selling it for under $400. The CrossCheck and the rest of the Surly line isn't fancy, but mine has held up to some real urban abuse and is going strong. The CrossCheck is also very versatile. Mine started life with a 7 speed internally geared hub, only to be modified into a single speed - both set-ups possible because of it's semi-horizontal dropouts. I could go on, but do a search... no doubt theres a myriad of info on the Surly line in these forums.
