If you have been waiting all your life to make a 720P HD projector from scratch, you can actually do that now for about $708. G&P Optoelectronics sells DIY HD projector kits, all of which you will need to make a full 720P HD projector. I sorta like idea for DIY HD projector except it’s still way over-priced for a DIY project. But it sure beats anything else out there on the market today.
