I know phones for sale aren't allowed on this site but anyone have any ideas where I could sell it other than eBay or Craigslist?
ebay to get the best audience for the $ but might not get as much for the device.
Craigslist or another local online site if you want it gone quick for the best $.
Do you frequent any other non-mobile relate forums? Try posting a for sale thread on those. Good Luck!

Its hard to beat Craigslist since they will come and pick up whatever you are selling and pay with cash.
As long as you don't mind personal contact with people.
