I just bought this bike. I think you're hard pressed to do better. Not that it's perfect...I think there are some strange component choices, but overall, it's a really nice bike at a reasonable price.
There are some good competitive options that I checked out prior to my purchase. Here they are.

The Specialized is very good, but also more expensive than the Felt. The Airborne is much less expensive, but it's not quite as fancy as the other 2. The Felt and Airborne both come with BB5 brakes, I had the shop change them out to BB7's (which is what the Crux comes with stock). The other curious selection by Felt was the crankset which uses a 130 BDC. This is coupled with 46/38 chainrings. CX bikes almost always come with a compact crankset to allow a smaller 'small' chainring. I had mine changed to a SRAM Force crankset with 46/34 chainrings. The 46/36 is more common, but I personally like having a bit lower gear at times. People say if you have to go to the really low gear, you should be running, not riding. I don't agree. When I'm on climbing on something that is loose and traction is at a premium, a really low gear and a high spin (similar to what you do on a mountain bike) keeps the rear hooked up better and is ultimately faster (for me).
So that's my take. I'm sure there are other options, but these are what I considered prior to my purchase.
