Well, although I had planned on picking up one of the 4500's, I decided to wait for a while to see if JVC fixes some of the issues with an updated unit.
If the fan noise wasn't so high after it running for a while, would have bought one.
Just didn't want to take the chance as it is quite an investment to have and not be 100% happy with. Then there is the hassle of selling it at a loss and replace it with someone other brand projector.
Yes, I could have gotten one of the latest JVC E-shift units, but wanted to stick with a true 4k projector, so the 675es is on the way.
Since the new Sony projector has a planned release of 1/2018, will see what happens between now and then.
In the meanwhile, the 675es will replace the 1100es to hold me over, and will sell the 675es when I pick up the new Sony or an updated JVC.
