To be honest, I use CL for all my Apple selling. I tend to buy one every year during the back to school promotion and sell it the next year before the promotion starts again. I find it much easier to do. I like getting the cash in hand and avoiding the eBay fees. It is often nerve-racking to deal with some of these people in person but i find that it often helps, especially if there are problems down the road. I sold my first macbook on ebay and the person complained about it and it turned out to be a big hassle. I find that if you sell on CL the person can be sure of the product that they are getting and are less likely to have problems because of missrepresentation. Just my 2 cents
And to add, I think it makes a difference where you are located. For example, I spend a lot of time in NH where there is no sales tax so I get my Apple products tax free but I go to school in Chicago where the tax is like 11%. I usually never lose money because many people who are not eligible for the student discount usually have to pay 1200 plus 11% tax. I get my macbook pros for $1100-$175 i usually get from the iPod touch. At the end of the day I dont lose any money. But again to emphasize I am selling in Chicago so the market is much bigger and there are more people looking. It would be different if you lived in the middle of nowhere where not as many people are looking to buy one. Good luck
