If you decide on the Cross Check, also take a look at the Soma Double Cross. Especially the Double Cross DC, which will work with either cantilever or disc brakes. IIRC, geometry is similar to the Cross Check. The steel tubing used in the Double Cross is slightly better; the Double Cross frame is about a half-pound lighter than the Cross Check, if you care about such things. The frame will accept 700c x 38 tires with fenders, so it makes a great all-weather bike. Especially if you get the DC model and install disc brakes.
With all the wet-weather riding I've had to do recently, I sure wish I had a Double Cross! My Cervelo RS is a sweet ride, but wet weather braking is scary and the lack of fenders means I spend almost as much time cleaning as riding...
