Again like mentioned above the older models wont goe stale. I have 3 Snes systems. My first one (made in Japan) is still perfect grey. My gamer system (made in Mexico) looks like i smoke 50 a day right in front of my Snes, and last my Snes junior (made in Japan) is still as grey as the day it left the factory. Guess it is something used in the manufacturing process, which consists of a cheaper or inferior plastic used in Mexico. Oh and just like the anti-smoking ads about yellow fingers there is absolutly no way to wash the colour off. Once yellow forever yellow.
