I posted in another forum about a technical question about it but I want to post here for this. How many of you have used or owned one of these? How's the image steadiness, sound, light output, and does it use some type of lamp that's been discontinued? How much do you think one of these should cost? These units come with a external amplifier and usually don't seem to be very common unless it's the "Devry Type Q" which seems to be the same projector but with a built in amp. I saw videos of the Devry 14000 and they seem unusually loud, unlike my Kodak which just purrs rather than chatters like gas powered wind up teeth. How about oiling? I would guess it's just the usual "Lubricated for life" (more like 5 years) nonsense.
