We have installed lots of the DWIN TV2's and i'm sure we will do lots of the TV3's they do have seperate on offs, input controls just about wverything you need. I prefer the look of the two piece unit like the dwin, just makes a cleaner install not having to run tons of wires up to the ceiling, also makes adding new equipment very easy. As far as reliability and tech support ya gotta love 'em if anything does happen to one of their projectors, rare but hey electronics break, i've never dealt with a better company when it comes to fixing a product and getting it back to the consumer.
