Many thanks Jim. It looks like the perfect device. Now I have to get it to South Africa somehow. Just for interest sake, our local supplier www.wantitall.co.za is charging $117 for the same product!!. I have sent them an email to say that they are despicable and blatantly ripping off the already over charged South African consumer. This is the story of our lives here. There seems to be the perception that as consumers of foreign marketed products, we are either stupidly ignorant or fabulously rich. Hence, the high prices of things.
I have just seen B&H sell it (although out of stock) so might go that route.
Best wishes
Sebastian
