^ BOOM! This.

AIS may have better resell value, but as noted... with such a short throw, not the best for us video users. AI in most cases will have the same optics with longer throws. Yes, they are older and perhaps some are less sharp. But majority are only shooting DSLRs. If you want tack sharp for 4k use, then you're budget is substantially higher.
