If you put it on Craigslist, don't list it for free. Then you have to deal with all the junk collectors... and those are some sketchy dudes that you really don't want coming around. List it for $50 (firm) and you'll get rid of it just as fast (or possibly faster, as you're more likely to attract someone who really wants it) and not have to deal with the CL riff-raff.
