Does a product like this exist? I'd have the PS3, cable box and a Aux going IN...I'd have a LCD TV and a projector going out. Sometimes I'm going to want the projector and sometimes I would want the LCD. I guess I'd need in a 3 (or 4) in to two out switch with HDMI? Does that make sense?

Well found it on monoprice but it's $90...Ugh, I was hoping $25 at the most...Might just go a different direction...

We probably have almost the same setup. I assume you have a receiver in between those components and the LCD/Projector?
