So i bought myne from ebay for reasonable 900€ and as far as i testet it, it is awsome. The newest PiTool gives me some kind of Bug (the one where the Picture dissorts in the middle of every screen) but the bug wasnt there in older versions so it should be fixeable by Pimax.
As by now i can only play Skyrim VR because my Vive set hastn arrived yet.
first impression was mindblowing and after installing some more mods (4k meshes and so on) it was OUTSTANDING 
I have NO regrets paying a Premium for it ,VR 2.0 here it is!!
everything worked like Charm from the beginning. Good work Pimax!! good work!
