Hi Iain, I think its hard to buy a projector that won't be up to scratch re. brightness... Look for education models which often have better warranties, pricing & lamp life. It can be a good idea to overspecify and run in eco mode which increases lamp life, and reduces running costs. The Casio lampless models might also be an option although they are more expensive, they are supposed to run for 20,000 hours. BECTA standards did require a minimum resolution of VGA. I have heard that there are issues with projectors being "too bright" for the classroom with a consequent risk of damaging pupils eyes which is why many education models won't exceed 2200 lumens (which is bright enough for a lights on presentation anyway). Here's an example of an education only model spec which seems to offer a 3 year lamp warranty and 5000 hour lamp life... as I say there are a range of similar models from all the main manufactuers, it just happened to be this one I found 1st..
