For years I used Pagestream 2.2 (free) and later I bought 4.1. It is a DTP-program. Usable for just text but also for a complex layout. I used it most for making worksheets or books for my pupils.
Besides multiple functions for text it is also possible to import graphics or to make complex drawings by yourself. On my Amiga it rocks. Now I'm using it on my Pegasos.
