I have Tangram book 1A, 1B, 2A, 2B (arbeitbuch &kursbuch) as well as Deutsch 1 (Inglingual exclusive learning book). I used them when I first learnt German 2 years ago.
They are still very good to use, especially Deutsch 1, 95% new.

Those are very good for beginners.

Tangram set: 15 euro
Deutsch 1: 8 euro
