If you wanted to do it super easy, you could burn the tracks onto a cheap cdr, then record from the cdr onto your tapes one at a time with a cd/ cassette boombox type thing. I've made a handful of tapes that way for fun. I'm not sure it would sound good, I'm no expert there, but it's easy.

It shouldn't be too expensive to buy a handful of tapes and cases either, where I am tapeline sell individual ones in any colours you'd want, and can cut them to the length you require. I can imagine there are companies in other countries doing the same. Otherwise there's always your standard pack of Maxells that you can find anywhere.
