san-sing, nice machine. It will do chain-stitching with the proper attachment. The attachment is around $10 on eBay and most sellers aren't aware of what it is. I use one as a back-up to my 403 and if I need better chain-stitching than my 20s will do, but don't use it as much as it warrants. Get it, you'll like it.
