Rod1,
I fly a Europa with a VP prop. It doesn't sound like exactly the same one - mine has an electric motor which I can use to gradually fine or coarsen the prop to any setting between two limits, it's not limited to just three settings the way you describe the one you're looking at.
I don't know what the official story is, and even if you don't officially need differences training your insurance company might insist on it. But even if it's not required, it's probably not a bad idea to get a check-out with a PFA coach, which will include any differences training you need. It will cost you £150 - £100 to the PFA, and £50 to your instructor, and that includes as much training as you need.
Have fun - the Europa is an excellent machine! Although the mono-wheel is much more fun...
