Seems like a decent deal, considering last model was on sale for around $10k two months ago:

Been researching UST projectors for a while, cheapeest 4K alternative is probably a Xiaomi 4K UST laser projector + screen which would be ~$4,500 total, but won't have the local warranty, which I think is 3 years with Hisense.
Other alternatives: Optoma P2 and Samsung LSP7T, both UST laser projectors releasing soon at around $6k, but doesn't come with the screen ($1-1.5k difference). Samsung is less bright than the Hisense or Optoma. This space is definitely getting crowded quickly.
The new Fengmi 4k Max (4500 ANSI with HDR10+ & HLG) is due to be released with a 100" screen. can get it for ~5000 Au stock!
