I agree with @
grolby. The Cross Check may not be sufficiently different. In particular, it's pretty darned heavy for a cyclocross frame. I had two Cross Checks. I built the first one with very lightweight wheels, so it rode pretty well, and the heavy frame plus the light wheels made it feel moderately light. The second build was too damned heavy, so I got rid of that one, too. But weight may not matter as much to you as it does to me. You may want to look at vintage frames, because you get a good value, and they tend to be lighter. My current main bike is a 1974 Raleigh International with all Reynolds 531 tubing. I weighed it and the Cross Check. The Raleigh fork weighs (barely more than) HALF as much as the Surly fork! The Raleigh was originally spaced at 120 mm in the rear, so I spread it to 130 mm. Of course, it doesn't take cantilever brakes, and I put dual-pivot brakes on it. I couldn't be more satisfied with the braking unless I had disc brakes.
