Just a quick post to let you know that my Sears Kenmore 1430 Zig Zag is back in my possession, and after some fiddling and studying I have it humming nicely on some scrap fabric. K is home "sick" (read: needing Mama time) today so I haven't been able to do any real sewing, but I will post when I get a chance to zip through a quick test project.
The word, through the fabric store owner, from the repairman, is that I have a good sturdy machine with a pretty stitch that, if I take care of it, will last me a lifetime. Cost: $50 for the machine at the thrift store; $84 for repairs. Score!
