I have a setup very similar to yours, and I could really use a switcher too. I have a lot of what I need built into my A/V preamp, but I could really use more. I have several A/V sources just like you, and only two A/V hookups. I have plenty of audio channels, but just two video channels so I really could use a switcher. I think I'll build one 'cause a metal box for shielding and a handful of connectors and switches is all I need. But if you find a commercial product that looks nice, please report back and I'll do the same.
