How do I sell this nice desk, Craigslist or eBay (or other)

I have a Techline office desk in very good condition that I wish to sell. However, I don’t know how much I should sell it for. I thought that one way to determine the price might be to put it up for bidding on eBay and thus let “the market” decide. What are the pros and cons of doing it this way?
Is it better to try to sell it on Craigslist or eBay? I’ve never sold (or bought) anything on eBay, so if eBay is the way to go, how do I get started?
