Legacy HMD from VRtifacts store... are they reliable?

[DevilMaster]

Some months ago I had posted a question about getting a Z800 to show at a retrocomputing exhibition. So far I haven't found any Z800 on Ebay (the only seller I found who claimed to be selling one was actually a scammer) and now I found a site called VRtifacts, which is about the history of VR and includes a store where one can buy legacy products. Did anyone here have any experience with them? In which case, did you find them to be reliable, and did the item(s) you bought work as described?

Bumping to ask one more question. How are transactions handled? I see no HTTPS link anywhere.

Sorry, never used them before.
