Thanks Thracian, I had done a few Googles for it but all the sites I came across gave specifications but no costs. It is a very user friendly piece of kit apart from a tendency to suddenly take a short cut when carrying out non-direct entries to approaches. I'm sitting there expecting it to parallel join procedure to reverse its course and it suddenly does a screaming Jesus turn to go outbound in the procedure, what's that all about! Anyhow, sorry for the thread drift Dick.
