Pretty much every thrift store and Craigslist area have tape decks. You have to wade a bit to find a decent one, but it's not too hard.
Yup, I've got a guy in mind. Repairs old electronics for a living and sells refurbs. I'll probably get one off of him, because I already know the part I need to fix mine doesn't exist. Just gotta find the time to make the trip out there.
