What do you want to spend?
http://www.localbiketrader.com/ is another resource.
You might also call the local bike shops and see if they have any Ruby's or Dolce's on consignment. Maybe put your name on a list in case any come in. (Though most shops, IME, aren't good at follow-through!).
A lot of shops take trade-ins. That way, you could ensure the bike is in good condition, too.
Also, you might wait a couple of weeks, and make a new offer for the Specialized you looked at. Prices drop if bikes are not sold.
Craigslist bikes change frequently, and the good ones go fast, check often.
