I know there are zillions of threads discussing pro/cons of getting higher end used bike vs, lower end brand new bike, but here i want to discuss a specific dilemma that i am considering.

Right now i am considering options for getting my 2nd bike and 1st FS.
For Specialized options, i can afford either a brand new 2009 FSRxc comp or a used Stumpjumper.
My first question is which used stumpy [production year / model (e.g. Comp,Elite,Pro,...)] combination with same price as new FSRxc is best to buy?
And second what do you think is a better buy: the new xc or the used stumpy?
