At the local Ace Hardware/Electric and Lowe's, they have black outlets and plates. Go give lowe's or a local electrical place a look, you should be able to find what ya need. ;)
I also used the parkland plastex for my screen. here's some shots from my measely 150 lumen projector: msur.home.mchsi.com/nemo.jpg msur.home.mchsi.com/theater8.jpg msur.home.mchsi.com/lk1.jpg *EDIT* It wont let me post links, or even images until i have 15 posts... go figure...
the lights are on for all the shots, except the screen shots. the flash on the camera kinda makes it looks dark except for where the flash is. :S i'll play around with it later, see if i can get some better pics. ;)
Well, my theater was done on the budget of a 19 year old college student, using ebay as my source for the reciever/speakers and projector. The screen is the stuff that's been talked about alot on AVS Forums and such. It's projecting ~69" picture. Future plans include, finishing and cleaning up...
