Thank you Ray.

My take on the reviews is the Z4 would be a better choice for larger rooms while the 900 better for smaller rooms. Conversely, 1.5 or greater distance than screen size, the Z4 wins, and at 1.5 or less, the 900 wins.

The 900 also wins with standard 480p TV viewing as the Z4 has some trouble de-interlacing.

But the Z4 has a 3 year warrantee while the 900 has a one year warrantee.

For my situation, it would appear that the 900 would be the better unit.

About some it up?
