AFAIK any decent projector these days can do CIH. The only advantage the panny’s have is the auto zoom feature that does it for you. Otherwise you just have to adjust it either manually at the projector (which would be a pain for most placements) or do it with the remote. Before locking yourself into a Panny for the auto zoom consider how often you’ll be switching between formats and how much of a pain it would be to do by hand or with the remote.

Also, why CIH, are you height constrained in your setup?
