It turns out the guy with the Adler 67-22L advertising business closure; the business was supposed to close April 6, 2019! He just keeps reposting. I saw an ad for a Pfaff 545 with a servo motor for $100, someone had already responded. Then someone gave me a heads-up for a Singer 111w155 with table etc., also for $100. but also it went immediately. 
 
	I googled Necchi industrial machines, and saw ones like my little BU Mira being sold as industrial, some even mounted in industrial tables with undermount motors, but I see they have true industrial models that look like they have the 11+" work table.  They seem rare in the US.   Are they as sweet as the BU Mira?  I have a tool fetish. I would imagine parts would be hard to come by.
