I love mine. If I had to get rid of all of my bikes except one, I'd keep the Steamroller. It's a fantastic all-around machine; can fit real chunky tires for gravely stuff or cross racing, but still handles pretty well with skinny tires for goin fast and stuff. My only complaints would be: rack and fender mounts would be nice, and it wouldn't hurt if they put the bottom bracket a little higher like the Big Block (Steamroller is the only bike I've had pedal strike on more than once).
But yeah as said above it's tough to go too far wrong with them. They're fun, durable, useful frames.
