For a tester project I need a DDS source, should be a module but with
some decent output power and if possible a display. SPI or RS232 style
control would be nice. So far I only found this kind:

Some comments are not so enthusing though:

Can't find a manual for it or any decent info. Does anyone know where,
or has a suggestion for a better module? Need 10kHz to 1MHz (higher
would be nice) range, 2Vrms or so sine wave into a 50ohms load. Price is
not so important, can be $100/module.
Hacking is no problem, for example to get around a RS232/USB chip
because I can't really use USB. Sine wave quality doesn't have to be
super stellar, slight distortion would be ok. But I can't use a big boxy
function generator since it has to be integrated in the tester.
