Books+cassettes, No pronunciation scores, Cheap, Intermediate
They published books of excerpts of newspaper writing in 60 less common languages ($40-80), and some excerpts of fiction. For each reading they include definitions of the vocabulary and translations to English. For languages where it is hard to find other courses, they also have grammar outlines.
This is a very useful way to learn words appropriate for keeping up with the news, though it would be a hard, sudden immersion for beginners. They have audio (such as cassette tapes) in most languages (originally $10-50), so if you can find them and have no other course in the language, you can study pronunciation with them, in order to talk, or to hear radio news. (Click for Arguelles' review of Dunwoody; he prepared their Korean books.)
They stopped publishing in 2012, but the books are still available from used bookstores.
