elihu23, get to a local bike shop and try out a three-speed. You'll find the gearing is much wider than 3-speeds in days of yore. The upright posture is a must for visibility in traffic, and is conducive to a more relaxed attitude once you arrive at work (in my experience.)
I drive a Breezer three-speed...fenders, chain guard, bell, front and rear generator lights, ring lock (!), strong rear rack, and I've added folding baskets. It's a pleasure to commute on this bike, rather than a chore. (Full disclosure: the routes I take are only mildly hilly.)
