Interact was the first to release a screen, and it got pretty good reviews, and as kennyb27 mentioned, Nintendo did show one last year at E3, and from what PGC said it looked incredible. Problem is, you have a better chance of hitting the lottery than seeing Nintendo release theirs. Now on to your third option, the Intec model. From the review I read on PGC the Intec was much better than the Interact. Cant remember any specifics but maybe you can find the review on PGC, or maybe you can ask Bloodworth.
