I wonder if the JVC's picture is better than the VPL-VW200 as 4k content isn't available for the masses. The build quality of the VPL-VW200 is very good: brass bushings for every screw (no plastic threads), great lens and beautifully crafted remote.
I bought mine at a really good price in late 2009 from ecost; it is the first display purchase I haven't had any regrets on (aside from the cricket noise). The picture still looks amazing. On a 110" screen, the VPL-VW200 brightness is perfect, but I'm thinking about building a large custom screen the next time I move so it may/may not be bright enough and I may have to re-evaluate things when I move in 6 years.
That said, if online vendors offer a refurbished VPL-VW1000ES for 75% off MSRP in 5 years, I'd consider it, but without significant price deductions on something with similar build quality to the VPL-VW200, I'm not going to switch.
