Smart girl! I think that's a wise choice. Riding aluminum just kills me...my hands begin to hurt after about half an hour. I can understand where it's use would be favorable, like for a crit or time trail bike, but for anything longer than that, there's just no beating steel. In my opinion, of course.
Definately can relate to the money thing...have you thought of getting a job at a shop? Pro deals on bikes are a great perk.
