Komatias, I've not got any plans to be down that area, but if I do happen to be, I'll give you a shout.

Boyan, the GSK990 (their 980 now appears to be a bus link unit only) is just a pretty basic control panel, whereas their 218MC-H or V control panel comes with E-stop,FRO,SSO,Cycle Start/Stop knobs/buttons. The only option listed for the 990, is an additional panel, which is just a precut frame for adding your own controls.
The reason I'm looking at the Chinese controller option, is I want a ready made control panel, and don't want to be faffing around making one. If I wanted to do that, I've got a KFlop+Kanalog+KStep sat in a cupboard, or a pair of Mesa boards lying around that would work well for this machine, but both of those involve trying to mount a PC in the machine.
