I used a Trek 3700 with hi pressure street tyres for about two years before buying a road bike. I would not look past this option as the front suspension and upright seating is very comfy plus being a mountain bike it is very tuff and takes a lot of abuse. I still commute on both bikes if it is wet out I take the mountain and if dry I take the roadie. Just as others said make the first one a fitted one from a reputible dealer. I bought one of the cheapest bikes in the trek line up and still received great service that went a long way with me.
