I have an awesome Late 2011 13″ MacBook Pro that runs perfect and has a small scuff on the CD slot side, but in perfect condition otherwise. The Mac is also covered under AppleCare until December 11, 2014 so if it has any issues you can take it to an Apple store or call phone support. It offers great performance in a small package and have been using it for Abelton and Photoshop use primarily and it rarely leaves my desk.
