I agree with Liza on the steel vs. aluminum comments. I race 'cross A LOT, and do it on an aluminum frame (actually two of them ). You would have to have a VERY SERIOUS crash to break an aluminum frame, and with the amount of carrying involved, it is MUCH lighter than the steel alternative (I am actually thinking about moving to carbon...).

Like others, my first road bikes were aluminum, and I loved them (till I discovered carbon). That said, my winter commuter is my old aluminum cross bike, and I put A LOT of road miles on it very comfortably.
