Does anyone have experience with this machine? I have a Singer 401a Slant-o-Matic and was looking for another machine for a backup. Joann's has them on sale now for $169.00 until the 23rd of Nov. I seen a thread here on BPL that they were selling on ebay for $148.95 for a refurbished one, for the extra $20.00 I'll buy a new one, if it's a decent machine. The YouTube video shows a guy sewing from one layer all the way up to 16 layers without any hesitation, it even sewed through a wooden yard stick without missing a beat. Just wanted to see if anyone has used one, and if so what they liked or disliked about the machine.
