More info on Phill Cartwright Banjo ukuleles

Hi all!

Now I have gone a-looking for another thread relating to this however it really didn't provide me with anything handy! So I was wondering if anyone here has at any time purchased from or played a Phill Cartwright banjo uke.
I was provided with a phone number that I haven't had a chance to ring as of yet:

Does anyone know what sort of prices he charges as I have seen then second hand for £800+?
Many thanks

I have never actually played one, but I have heard wonderful things and seen photos that are beautiful.
