I ride a Cross Check with gears and I love it! It has been my primary commuter vehicle for approximately the last 5 years. I've never ridden the Kilo so I can't really compare the two. I would say, though, that if you want a single speed Cross Check it would make more sense to buy it as a frame set and build it up that way rather than buying the complete (geared) kit and stripping off the derailleurs and converting it to singlespeed.
