I am also thinking about upgrading from a 10HT. Honestly I think most people on this forum already have. I will probably wait for my bulb to die, and I have had my eye on the AE900. I am tempted to wait for 1080P LCD, but its getting harder to wait. I have not auditioned the AE900 yet, but plan on doing so after the holidays. Hopefully AVS will have one available to look at.
