I've had one of the 1st gen cast iron Unimats for decades but I'm not obsessive about collecting all the accessories for it. I have the power feed base and the vintage E16 collet chuck and 8 collets, plus the three-jaw, and that's all I really want. I think when Emco started getting into the complicated threading attachments and stuff they kind of went overboard. But I have made many small parts with mine over the years, it's a great little tool.
