I've got mine working now (sort of) - the outputs were labelled the wrong way round!

Trouble is, it's not working well at all for me, even though my settings seem to be identical to Brian's. Basically, when I send a command it gets repeated three times, so moving the menu cursor up just one line is impossible. I need to check with the supplier.

I think mine was something like £80, but it's a dual output one with pass-through.
