I don't know or care for anything about High School Musical, but Mattel does make the dolls with better heads and faces than the current Barbie line. At $5 a pair, I went ahead and bought a few sets for the heads.
Even the dolls I cherry-picked have paint problems that were not obvious in the store. Sadly, $5 is about what the pairs are worth, if that. I've seen clone dolls with better quality clothing.
