It's a shame they can't make a reasonably price projector that does everything well. I guess you always have to weigh what is most important to you.
I bet the picture on your new projector is fantastic for everything except those darkest of scenes with white highlights in them. I think you've chosen the right approach to get this projector now then get a UHD JVC later when they come out. You will have best of both worlds then.
Were you able to compare the carada bw as well?
