I need some advice. Right now I'm using a 20" Sony Wega TV (way too small, even for my little room, but I can't afford an upgrade yet) and a Technics SA-DX950 receiver that doesn't do S-video switching. All of my sources, however, use S-video. My question is whether or not I should buy an S-video switcher or just deal with plugging and unplugging each of my sources. Will an s-video switcher cause any noticeable degredation in picture quality? Are there any in specific brands that I should buy? Thanks in advance for any advice.
