The E16.7 is a fine machine and the technology is nice, but the personal view screen is really not worth the money in my opinion.
A personal view screen for an additional $400 is not really worth the money in my opinion. You can purchase a 42" LCD tv can be had for about the same money and mounted on the wall in front of the machine. Other than that the E 16.7 gives you good quality, a good warranty and great features outside of the personal view screen. All in all it's not a bad value for the money.
