Why are you only looking on Craigslist? There are 5x more private party sales on FBM, at least.
Are you ethically opposed to Facebook? It's a tool for buying stuff even if you don't want to use the "social" part. And you could use a fake name... my cousin's husband was "Pop Corn" for a while.
Craigslist around here is dead. Offer Up is another option.
