The price i got was £1262 for the GSK980MDc direct from GSK, the other Newker NEW990TDb was on Ebay £450 ish. Aliexpress appears to be for retail punters while Alibaba appears to be set up more for traders. I found GSK gear only on Alibaba. Of the Chinese controllers GSK appears to be the premier brand for the machine builders. For lathes with automatic tool change GSK980TDb, and milling machines GSK980MDc. I think if i do buy i would be happier buying from the manufacturer. In your experience will they negotiate on price?
