There is a few for sale on eBay.

I've found one on eBay for 1400$ Aus. That's utterly crazy when I saw one for 650$ the day before but it sold. From what I've been told 500+ is about right for it. 

It's possible I can't see them cause they don't deliver to Aus. 

The ones I found was in Germany, the UK and one in Denmark. I found one locally om Facebook Market three weeks ago. Mint condition and including both the floor stand and desk charger. One had a lucky day :)

I'm going to ask my sister to look from Ireland. She might have better luck with it. The one that shows up for me is from the US.

Hey, I literally emailed the seller 5 mins before you posted. He only delivers to the UK. Thanks though. 

I´ve had that with german sellers as well. And I really don´t understand why they won´t send outside their own country, when you want to pay for the shipping! I live in Denmark, so I can act as the "middleman" - would be glad to help though.

This one expensive, but fully functional - and from Denmark.
