Yes pcs looks good... I am not sure where pcs get their prices from for audio connectors.. everything costs as an extra with pcs even rca connectors. I suppose it keeps profit margins a bit higher which they probably have to do.

Also this is nice looking from dutch rf shop at least seems to be clean and more serviceable but it would be nice if they could knock up a little encoder for €35 or so

They don't seem to sell stereo encoders for it.
