Thanks for all the replies ... some interesting programs I've never heard off ..
I've been playing around with
http://www.notamcheck.com/ Which plots the NOTAMS in real size and shape to scale on maps showing the route, very neat for £20 one off fee.
Its one of the clearest presentations I've seen.
I already own Navbox, but you have to be a database subscriber to access the Notam features which I am not.
