S5
From an initial play with the tool, this looks very useful. You create a single html file and through the use of DIV tags as many slides as are needed are created. You can also tag text/images as 'handout' which means that they will only appear when printed. You do require some basic html knowledge - eg about applying style tags, but to anyone who is familiar with heading styles in Word should be able to cope.
