It's been maybe 3 years since i've been on a bike and i think it's time to get off my lazy a.. and get back on the road and back in shape. I've forgotten about a lot about bikes, what's good and what's not. But im hoping to get some help here.

The things i am looking for:
48cm frame
at least 105 group or up (older stuff is okay)
alum frame/alum with carbon


budget is around 800. also making it an older bike (dont think i can get what i want for the price i want, new)

I had a 2006 specialized s-works e-5, i really liked that frame, so i'd like to get a frame similar to that if not better.
