Buy a used commuter on ebay and personalize it. I have purchased two older, (one early 90s, one mid-late 80s) cannondale roadbikes, (I'll take pics). I don't want my commuter to look too new or too fancy as I lock it up outside. I had mustache handlebars on it at one point, but went back to drop, I throw stickers on it at will, if I wish, and my tire choice are specialized armadillos for lasting power. Of course, I live in SF and must contend with hills, so I prefer a light enough ride. I am about to sell one of these two cannondales because I can no longer store 2. I'm very torn over which one to give up and I will take and post pics of both and ask you guys your opinion. For now, I ride the blue one it is so comfortable and sporty! Pics on the way. Good luck in your choice. If it were me, I would by a used aluminum roadbike - maybe 10-20 yrs old in good shape, maybe switch out to 25 or 28 size tires, from 23 (thickness), maybe put mtn bike handlebars, put fenders, If neccessary, and a rack that suspends just from the seatpost, a cheap odometer, lights, maybe some glow in the dark stickers for fun, and H2O cages - done!
