FunkyMonkey:
Thanks. Way out of my price league unfortunately.
Given that my screens size and throw distance will not require such brightness, I shall wait till there are some (lower spec ones available) that are more on price parity with 3D TV's.
I believe the JVC ones are available now also, they're certainly shown on dealer pages ready to buy - though the price is going to be in line with, and over that of, the Sony.
No doubt the PJ manufacturers will be flooding the market with shiny new 3D capable PJ's next year, at which point I would expect the current crop to tumble in price also.
