I have both the Infocus ls110 and Dreamvision cinexone in my show room. I was really glad to compare both units. I have also sold the DV with the optimizer and found it to be very good. Both units perform very well and I have found both units would appeal to different customers and set-ups. The cinexone is less expensive and you can sell the optimizer later to break up the cost. Just don't forget the db-15 extension from the projector to the optimizer! The ceiling bracket is crap though ( i had to shim the side of the projector with a paper match inside the bracket! ) The ls-110 dcdi was made by faroudja and that does make a difference. I have it playing both HD and 480p using the Philips q-50 dvd ( dcdi by faroudja again)really nice!
Tip: watch out for very bright units ( sharp,sanyo etc..) when used for older play back material ( gomer pile stuff) the grain seems really more evident and uses up the old bulb life sooner ( unless you can reduce it in the menu of the unit like both of the aformentioned projectors )
