Sometime this summer I will be building a home theater in the basement. I plan on buying an LCD projector this fall. How do I know where to leave a hole for the projector and where to run the wires? I know some projectors come furinished with wires so would I be duplicating effort if I ran a set myself. Or is it better to get the projector now? I was thinking about the sony hs10 or the panasonic l300u. However, I was hoping by this fall another batch of new models would be out. Thanks much.
