The review answers your first question so maybe you should reread the article.
I found one on ebay. I did not test it on the ps2 though I do not see why it would not work. The wii is close in output to the ps2 as both can do 480p max. And the wii tested fine. The “best” image quality is going to be native. The cool thing about the high-box is that you can have it display in a “native” mode so it should look fine. Based on my experiences you should be fine.
