I will be traveling via airplane to see my wife's family over Christmas, and I'd really like to take some type of entertainment with me. I currently have CoD4 and both Knights of the Old Republic games on my rMBP (13" 2015). I may also download borderlands again. What is the best affordable controller for use with a Mac? Yes, price is a factor because the controller will likely only be for occasional use (when traveling). A Mouse is not an option. Thoughts? Thanks in advance.
