That's a great deal for that projector especially when you compare the price point to the Hisense model. I would much rather have the Sony. However, $15k is $15k no matter how you slice it and I would be worried about spending that much on a unit that is not very future proof with 8k and HDMI 2.1 already here. Replacing a $3k unit when it becomes outdated is a much easier pill to swallow. At the end of the day, only you can answer how much it's worth to you.
