I just picked up a Singer Touch and Sew model 628 along with a box of cams, bobbins, and attachments for a few bucks at a thrift shop. It's missing the power cord but I did open it up top and bottom and the plastic gears appear to be working. Tension seems ok, I sewed a few stitches manually but guess I won't really know until I get the power cord. I'm reading a lot of mixed reviews on this machine, is it worth it for me to go ahead and buy a power cord and see if it it works? Any information anyone would like to share on this machine? Thoughts or suggestions?
