alright guys...

I'm really wanting to get started in the DIY projector world but I'm a little scared of making any big purchases right away. Let me know what you think of this.

I've already got a professional 60" wide pull down screen and a 3M High power OHP. I was wondering if I could just build an enclosure around it between the "face" of the OHP and the lens to keep light from leaking all over the place and use the standard psOne lcd screen mounted somewhere inside (with proper cooling of course).

My intended purpose: since my intended purpose may determine whether or not you would give me the ok I thought I should post it here. I do not care to use it as a computer screen or watch it any other time than at night with all the lights turned off in the house. I would prefer to have it behind my couch which would be about 13' from the screen and hopefully give an image about 75" in diameter to fill the screen.

I don't mind using the standard composite video input as I'm thinking perhaps it will "soften" some of the flaws of the image due to the lower resolution of the panel. My main concern otherwise is will it be able to be bright enough? I've used an OHP with the older projection panels but I don't know if using an actual LCD will allow more light through than the old projection panels will...I know this OHP is brighter than the old one I used before..I believe its the 9800 series?
