Newbie, I just started rode biking about 1 1/2 years ago. My first bike was the Trek 1.2. I paid about $750 new for it. I was not for sure I wanted to stick with biking but the more I ride the more I like it. If you think you will stick with it I would think about the 2.1. Where the 1.2 is ok if you ride many hills or want to ride with a group the 2.1 will serve you better. Just my thoughts.
