What are you putting through it? If it's only ever PowerPoint slides then almost anything will do (resolution and latency are pointless if your slides are only 1024x768 to start with).

For 'pro' users there's a whole pile of tech issues to dribble over, like HD/composite support or audio - but if you're carrying something around for training then you'll be more bothered about the throw ratios - how wide, narrow or angled the image can be. It's useless having a bright projector in a small room if the biggest image it can throw is only a few feet wide or it can't cope with being pointed up at a steep angle because nobody has anything to balance it on. I've also had to work with some which clearly weren't designed to be moved about, as things like feet keep falling off.

Cost of lamps is the biggie for company users - they're coming down but if you hike the things about in the back of a car, or keep turning them on and off when still cooling, high-power lamps tend to go pouf. If you're not careful you can spend more on a spare couple of lamps than the projector cost.

Have you considered a large flat screen TV, with the appropriate hook ups for Pc/laptop with dvdplayer even video( video!!!).

Add a webcam and you have teleconferencing facility.
( dual value good for selling it to a/cs!)

If u get either remember, sound from a laptop rarely good enough for showing training clips, you will need speakers and amp, but TV sound is much better.

agree on the lamp/bulb issue cheap projector expensive lamps.

And 8 hour use 5 days a week soon eats in to a 2000hour lamp life.( when training i rarely turn off projector, can cancel projection but turning on and off is the kiss of death for lamps.
