There's a nice long thread on here about using the Pebble Steel bands rather than the Moto's (because it was the only option for months after the 360 release). In addition to the cheaper price, I would even argue, it's a more attractive band. Of course, that's my personal opinion. I wouldn't sweat getting cracks too much if I were you. I've had mine since launch week, with no cracks, and people with the original leather band have reported cracks on their watches. I have a hard time attributing cracks on the watches to installing the Pebble Steel band.
