I read the advice given in a review written by a user of the Talk Now Brazilian Portuguese, which also mentions the European Portuguese version, and decided to follow it, that is I bought Manuela Cook's books together with the Talk Now Portuguese. I am quite happy with the results. Talk Now is a lot of fun and good practice but it does not teach you the language, it is more like a complement to a course for extra practice. Without MC's books I would have been rather lost but the Talk Now goes well with them. Very enjoyable! I am very happy to recommend it (but for practice, not to actually learn the language)!
