Having recently gone through liquidating all the large or $$$ items from my father's estate, I would recommend Ebay over Craigslist.
Ebay gives you more eyes and buyers have to pay upfront and there isn't any haggling.
the no-shows and lowballers got old really fast for anything I listed on CL.
I came out slightly ahead using Ebay, even after the fees.
Best of all, I was able to sell everything inside of a month.
Sorry to hear about your friend, I hope this is helpful.
