OK, here's my two-cents. I have just finished my theater and thanks to all here avoided some pit-falls. I did miss two things pointed out in this thread and I have been able to resolve one rather easily. I did not put a switch on the outlet for the projector and since the fan does not ever go completely off I had to keep using the projector on/off switch. I found a remote control outlet at lightingswitch.com and it works just as advertised. Now I don't need to worry about throwing the projector out of alignment playing with the switch. Also, would have made the risers just about 1 inch or so higher, not a big deal at this point but in hindsight I would have gone to about 8 inches rather than the 6 and 7/8's I did use. Thats about it, if I think of more I'll be sure to come back. JR Can't post a URL yet but the cinema is in the galleries titled Rowland Cinema.
