Actually Pimax 8K 2nd gen headsets start shipping the end of this month for kickstarter backers,I'm sure more than a few of these will hit the ebay open market as well.
From the Pimax news letter.....
"0 days countdown - M2 in-depth reviews are coming up from mid-Sep
The crew is back to the office! After the meetup with over 100 enthusiastic backers in Berlin, the team looks calm but still thrilled inside.
The participants of the meetup, including our lovely volunteers, are all Pimax backers. Glad to find our backers are real VR enthusiasts who are not only passionate but also knowledgeable about VR. During the meetup, people were chatting with each other like old friends about all the VR topics. The meetup cannot have been so successful without the passion and support from you!
Moreover, the M2 devices we showcased in the meetup are exactly the result of the collective power of the community, especially the M1 closed beta group. For the past three months, the testers dedicated their valuable hours every single day in testing in addition to their own very busy schedule. The efforts of the testers are all about to deliver the best possible headsets to Berlin, and to your doorstep in the near future.
For the rest of the days on September, the team will focus on production and delivery, also manage to speed up the software iterations. The Kickstarter shipping will start by the end of September.
We already have several top voted cities from the community. The time and location of the next meetup will be disclosed when confirmed.
The testers you met in Berlin, Thomas, Sebastian, and Martin, are now working on M2 review videos for all the backers.
