Hello,
Bought February 2017. Asking for 550€ + shipping (from Switzerland)
I am very happy with the device as an e-reader for PDF's. When I bought it I finally read a few books I kept aside but now I wish it would be faster to conveniently search inside books for things you need 'ad-hoc'. I have a library of over a hundred specs sheets in PDF which I refer to every now and again but I found myself to use PC for that instead for e-reader. It is too slow to search for information across your library on the device. I can see that devices for professional use are in plans from few vendors so I think a year or two from now I would be able to buy a device which will suit me better.
In the mean time I have adapted a very nice app for the e-reader which I would recommend for anyone having more than a few files on the device.

PM me if you are interested to discuss the shipping/payment options. I may also send it from EU if you don't mind some delay. You can also PM me your offer if it's different, I will not even reply to all such messages but who knows
