Thanks for the responses guys. That Diamondback is worth a look. I think I prefer the larger wheels of the Smoke, but I'm not trilled about the riveted chainrings on it (precludes any possibility of replacing rings without a full crank upgrade). Although, I've never worn out a chainring, and I ride a significant amount (so, maybe it's a non-issue). The Marin looks pretty sweet also, although I'd prefer rim brakes. It looks a bit more off-road capable than the Smoke. The Kona *seems* like less of a thief-magnet too...

Thanks again.
