This is what I use for my website ( http://autolicio.us ):
http://sfbay.craigslist.org/eby/ctd/2114911822.html
I did a bunch of testing and this page had the highest conversion rate by a far stretch.
There are a lot of other services that do this. Postlets is the big one. Most of them go beyond the copy/paste model. They will actually post for you, track your ads, repost when expired, track conversion, etc.
There should be something similar for other categories. (And when you're done, move onto eBay auctions!)
I'd at least expect them to come after you for the name if you get any traction - best to have a backup one ready.
