business projector versus a haunt theater projector? Is there that much of a difference in black levels?

I am confuse near your question. Are you saying you can afford a $2000 projector OR can't afford?

Try using a home theatre projector if you can. The bussiness projectors are not meant for movies. They're meant for slink shows and a small movie clip.

Now you can get a decent Epson projector i.e. around $3500 Canadian dollars with a $300 discount right very soon. I believe the model is the Epson 1080. Epson makes a decent projector.

Ofcourse you can opt to capture the cheaper projector. I have personally seen the Epson 1080 and it does a great mission on the big screen.

Here are also some decent screen about. I consider you should provision more for your screen though. Try to think $1000 all for a surface. They a decent Draper screen would serve you well.

On the other foot you can also paint the wall matte light and it should work As well. You can try looking for the "goo"-this stuff is supposedly able to serve as a screen.
