Hey, congrats on the marriage... Welcome to the ranks. :P
As for your question about an multi-switcher. I have one to suggest that is
probably the best one I've ever seen (I've been very happy with it since
I got it). It's the RCA Video Source Selector model VH920
RCA's website has this description on it:
"Take your audio/video system from "oh no" to organized with RCA's
Video Source Selector. It lets you attach up to 6 S-Video or composite
audio/video sources and easily switch between them, eliminating cable
swapping, splitters and other annoyances. There's even a convenient
front mounted input for connecting camcorders, digital cameras and
video games."
