<p>Thanks again Ray, that's cleared things a lot (I was told I'd need the plate by an ebayer selling an H20--no wonder I've been unable to find one)<br>
It would seem, for my purpose, an H20 otl. would be the one, I'll most likely be using at home and, as I said, tethering is not a problem. <br>
I feel I'm getting there now, it's a simpler job looking for V mount backs, will keep the Forum posted of my progress. </p>
