I have a old singer 66 that I have been using to sew on 8oz leather belt ends. It's slow going but gets the job done. As I am expanding my business I am looking into buying a consew 206RB-5 used or new. Any thoughts? I just need to sew on leather belt ends but need to have the capability to reverse the machine to be able to tack down the stiches and be able to go slow at certain points. I am a small business owner just starting up my business. The local cobblers leave feed marks on the belt ends , thus the reason I have been using my old singer.
