Vava Short Throw Projectors

I am building my third house in the last 10 years.  All three houses had a theater room with anywhere between a 125" - 135" screen.  My last two houses I used Epson Projectors -- the last being the 10500 laser projector.  The quality of the picture was very good but I am looking to try something different.  My two choices were Sony and JVC.  Sony is true 4K and I was considering the VW695ES or VW885ES.  The 885 retails for $25k.  For JVC I was considering the NX7 or NX9.   The bottom line is I would be spending anywhere between $8k and $19k for any of those projectors.

Enter VAVA 4K short throw projectors with 6000 lumens for $2800.  It works with screens from 100 to 150 inches.  My new house will have a 130" screen with Tekton Double Impact 5.2.2 speakers.  Does anyone have any experience with the VAVA projector.  I just wonder how the picture quality is versus say Sony or JVC or any other projector.  I want a great bright picture.  It just seems too good to be true especially for the price.  Comments about VAVA would be greatly appreciative.  You can also comment on Sony vs JVC.   Thanks.
