I really like this projector. First, most of the projectors I've gotten to review this fall are primarily upgrades of last year's models. A little better, a little less expensive, and a new feature, here and there. The HD8600, by comparison, is a brand new projector.
It's not easy being a brand new model in the Optoma's price range. As an $7500 (or more, depending on lens) projector, it faces some very stiff competition.
As it turns out, though, Optoma is up to the challenge. It is certainly a serious contender. It's bright, has extremely good color, and a a vibrant look and feel.
