A&A seems to have a fair assortment of Cyma guns as well.
Just started working, and not sure if I should go with TM or Cyma.
Wood Comparison:
Stock Cyma AK Folding Stock
TM AK-47S
It'll be about another week before I can afford either, so hopefully someone can put out some recent info on the new Cyma Generation (At risk of being disowned from ASC :-D )
P.S.
Here's a translated review on the cyma AK47S

EDIT: Yeah, I know this isn't about the MP5-J, but it's the same brand of recent guns to hit the market.
