I know the ICON and 3k NAM have their own as well. So I guess you can throw the herpes into that mix as well.
weather.us has some rare Euro maps you won't find elsewhere. There's a significant weather map there which makes me think the euro does put something out for ptype...since the maps include t'storms and fog as well. I doubt the US vendors are getting ALL of the euro data. I mean weather.us has heat flux, moisture flux, ozone, etc.
