I currently commute on a surly Cross-check which fits me like a glove, but as you said its not a terribly universal fit. Before buying my Surly, my favorite frame maker was Kona. I think that Kona has a nice lineup of some pretty versatile frames. I have also been checking out a couple of Salsa frames that I have spotted at work and they are pretty nice, I would recommend checking out the LaCruz
