I have a white MacBook that I bought in July of 2007 and was wondering what a fair price to sell it on craigslist would be. It's 2.16 GHz I believe and I upgraded the ram to 4GB and the HDD to 250GB. It runs the latest version of OS X w/ a fresh install. Just looking to put on craigslist and need a price that won't fuck me as well as so it won't just sit on craigslist for 30 days w/o a call. Thanks.
