My two commuters (the FG is a cross-post if you hang out in SSFG at all):

Motobecane Fantom Cross:

Completely stock except the Brooks, Planet Bike fenders and Campus SPD pedals. Going on 3 years of ownership - still happy with my purchase. It's no LHT, but I've gotten it to the point that I can ride it for pretty substantial distances. I commute on it 3/4 times a week, when I'm not riding my FG.

My Fixed Gear:

Performance SSR frame, Michelin City 28c tires (about as big as you can fit), Formula hubs laced to CXP22's and a bunch of other parts I had laying around. I'm pretty hip.
