For a couple hundred bucks - used is the only option that makes sense, and its a good option. Shop around, sometimes you can get a bike that sold for 7 or 800 bucks a couple years ago for that. If you go the used route be careful around fit, get a LBS to show you what size frame you need for starters. Otherwise I agree, save and wait...the fitting that a decent LBS provides with purchase is very valuable when you're starting out.
