Hello everyone! I know I'm not eligible for the MR marketplace, but am looking to sell my mid-2011 13" Air. I love the portability and the everything, but am finding myself drifting back into heavier photo and video editing that I stopped doing up until recently. I'd like to upgrade to a 15" pro. That said, what are some good (Mac specific?) buy/sell/trade sites that I could check out? FYI: I've already got mentions on craigslist and eBay. Thanks for any info.
