Re prices of these sound modules.
In OZ, (today), the Graupner is AU$337, (from Cornwall boats), and the Canadian one is AU$215. (

No Contest whatever, especially as the Canadian unit out ranks the Graupner with features by far.
Where I sit, a MUCH better deal, as the service from both countries to Australia, at best can be questionable, or as usual from the companies I normally deal with, superlative.
The Canadian one gets my dollars, and tonight.
Sounds stupid, I know, but in all the years I've been on-line, I've been dudded once, (by an English company who shall remain nameless).
Just thought you would like to know.
Best regards to all,
Steam Head.
