Just a note on scaling chips. I have a 720P DLP projector with a good scaler and through component the Wii looks great at 480P projected 10 feet wide. The 480i image suffers a little due to the lower resolution. Luckily most games are 480P compatible now.
Having seen the Wii on many TVs I can tell you that the scaling chip is very important to how a low def image ends up looking. A poor scaling chip can wreck an image. Below is a link to a nice description of just how much a scaling chip does. In my case it almost performs miracles on the inputs to my projector even S-video upscaled looks great.
