Emerson Swingmate Cobra Portable Turntable

[tvcollector]

Don't think this is antique yet.. So I picked this up at a goodwill about 4 or 5 years ago.. It's missing the needle and the whole cartridge.. Plugged it in and I hear it turn on and the arm goes back into place as it should.. I would like to get this thing working,. Does anyone know where I can pick up the whole cartridge and needle for this thing? I did a google search and saw some models like this with stackable option.. Let me know.. Thanks..
