I have a hobbymatic 947, that I have had for over 20 years, bought it used in AK for $400. it works great and have never had a problem with it. mine does not Have IDT, but does a nice stitch, has about 20 stitches, most I have never used. I used to use it for classes as it was fairly light weight (untill I got my FW, will use that for classes now). mine weighs 15 pounds, I still love my little Hobbymatic, and will keep it, hope this helps.
