The most important thing will be to get a bike that fits you properly. If that Trek fits you, it would be an inexpensive way to start...you can always upgrade components over time as you see fit.
For a new bike you might consider looking at the Giant OCR3 or OCR2 at the sub $900 price point (it also has a women specific version, so you can compare to the men's version to see which fits you best).
Thing is, even at 10 years old, that Trek is a nice bike, if it hasn't been trashed. It will definitely be lighter than any new entry level bike.
Ignore Velo Dog, I think he needs a hug.
