The agent in the UK for Golmatic was (is?) Brian Tate of Pro-Machine Tools fame. I get the impression that he is winding down the business but may still respond to his facebook page. If you can find him, he might be able to give you some opinions about Golmatic.
I can say for what its worth, I did make a cursory examination of one of these products 20 years ago and thought it look a decent bit of kit, albeit rather too pricey for me at the time. But what I knew about machine tools then would have fitted on the back of a postage stamp, so don't give this comment too much weight.
