I don't yet have a CX bike, but that is the next type of bike on my list--because we have a lot of crappy and unpaved roads, but also to maybe try some racing.
I've been looking at Cannondale's offerings. I've been very happy with my Cdale road bike and I could get a pretty decent bike for the price. Redline is on my list, too. Our favorite shop also carries Salsa and Surly, but they are more $$ and I believe are heavier bikes, too.
