Local Goodwill has a bunch of these Maxell C45 AV cassettes, sealed in original cellophane packaging. Not familiar with the quality but they look cool. They're selling them as a set of 3 for $2.25, they have about 6 sets of 3 (18 cassettes) if anyone is interested I can pick these up for you.
Here's a picture I found online of what the cassette looks like.
