Hi Barmoor, I've only just figured out how to get back on here!
I got my Speedtouch from click here They are B grade but are like new. They aren't showing as available just now but they may be doing a stock take, if you ring them they may actually be in stock.
I don't know how you feel about Ebay but there a few knocking around on there too.
I notice they have brought out a v7 version click here. but I can't vouch for this as I don't know anyone who has tried it out yet.
