The school I work at is planning to purchase a projector system in the next few months. Not being up on the latest and greatest in this area of HT, I thought I would appeal to the wisdom here at HTF. Primary use will be a 50/50 mix between video/dvd presentation in a darkened auditorium (lights dimmed but not out for obvious reasons , and classroom powerpoint or other computer-based presentations (so-so light control, with overhead flourescents). The current model being looked at is a newer Mitsu that they're asking $3400 for (1200 lumens, digital - not lcd, don't recall the model #). Any specific recommendations and/or helpful suggestions would be appreciated. Thanks!
