G-System

Have always known about the existence of the G System kits but really need to hear what they are like from a person who has actually ordered from them.
I hear that they are a company in Hong Kong (?) making kits without Bandai/Sunrise permission. Having a rummage around Yahoo Auction Japan and 2Channel, I find that Bandai are apparently turning a blind eye to this situation.

The kits on G Systems site look fantastic though. One of the kits is going for 2,500 USD. Understandably, I want to know more about the company and the kits before I buy. Anybody own one of these kits or have had dealings with them?
