No idea what the Chinese Company are like but you would need to do your homework on them. Other problem is going to be support for the machine, best your going to get by buying from China is phone support which may not be easy to understand. You will still need someone with some sort of understanding of the machine parts both mechanical & electronic.

Just out of interest do you already have all the equipment you need to do the carbon fibre work & someone with the expertise to use it??
