Projector for Classroom

[raviuoh]

Hey,

I am looking for a budget projector to project content created using a lightboard.

Some videos:

I need some suggestions regarding:
1) Projector for bright classroom
2) Screen(DIY/Market), I can change the background in video to green or marker if that helps in getting optimised solution



Should i go for dlp or 3lcd? any brand suggestions or specific models?

Thanks for your time.
