Unfortunately you're mostly just seeking a good deal at the wrong time for bikes. I'd highly encourage visiting some local bike shops (hopefully you have some choices) and see what they may have, even for used deals. If they've gone thru the bike could be a definite bonus to save you some grief, too.
@BoredSysAdmin what he is saying here is to not overlook the value added from using a bike shop, particularly for a noob that may not know what they want/need, and may not know how to properly check and maintain a bike.
You will pay a bit more, but you pay for the service and the shop as much as for the bike itself.
A GOOD bike shop is MOST interested in getting the RIGHT bike for you! They should be there to help get you the right bike, the right fit, service after the sell, and generally serve the community, not just make a sell and move along.
And, just like any hobby, you won't know what you really want/need, and how much you really need to spend to get it, until you get started, get time on the bike, and start to understand what the extra $ gains you in performance.
