This is what I have by the way:
It's a 2009 Jamis Satellite. It's got a Chromoly steel frame, which is a little bit heavier than aluminum, however it provides a little smoother of a ride. And I'm pretty sure it has Shimano Tiagra all around for components..however it might have a Shimano Sora Front Derailleur. Those are entry level components. A lot of more experienced riders will complain about them not shifting smoothly and being a little heavier than nicer components, however as an entry level rider I probably couldn't tell much of a difference anyway.
I hope I could help you a little bit. Do a lot of research and figure out what YOU really need. Try going to your local bike shop and asking a lot of questions. But don't get talked into spending a lot of money haha. Good luck!
