Distribution using Baluns

Are these any good?

Google "cyberselect.co.uk/product/797"

can they be used for composite too? I'll need to connect my old tv's up until I manage to get some LCD tv's with component.

And as i have 2 or 3 tv's around the house, and 2 or 3 inputs... do i require some sort of splitter or switcher? anyone recommend a low budget solution?
