The "youth version" is a new release from Noob, the factory is having a promotion to look back on the old times when Noobs were at that price, hence the "nostalgic" price.
Taking a guess, I doubt its a new version.

It's a new version you can see that from the pics lot of updated details / fixed stuff and looks more like a ZZF than other Noob subs.
Dealer. Unless you speak mandarin, just avoid dealing with them.

Just asked Eric at GeekTime for QC photos of the Noob YEE. The dial font is thiccc as all heck but it seems a fair budget option for most.
