I'd go for the Poprad- steel frame, nice handling bike. Cyclocross bikes get banged around and abused quite a bit in races, and Aluminum frames, though maybe a little lighter than steel, also dent more easily and have a more limited fatigue life, especially for cyclocross rough use. If you're not racing cyclocross, then this is mostly a moot point, but I'd still go for the Lemond for an all around do everything bike, you'll find it more comfortable than the Cannondale. Don't worry so much about the components, the differences are not that big a deal. Try both bikes out to see the diff in how they ride, but make sure you have the same wheels on for the test for fair comparison.
