Chinese AEGs are demonstrating themselves to be on-par with most HK and Japanese manufactured brands, with more upgrades out of the box, for half the cost. Why does this surprise you?
For the money I save buying a Chinese clone that's indistinguishable from a TM, I can replace anything that eventually breaks on it and still be ahead over buying a stock TM. Also TM is so sluggish with getting any new idea to market that by the time they have a working model of something, Chinese companies have them on store shelves.
The big name manufacturers' days are numbered and they know it. Just look at the prices at
www.gunnerairsoft.com for proof (and he's MAKING money at those prices).
