I have been trying sigma cutters for around a year or so and i have finally come to the conclusion that they are not for me. I have to say i can't fault the cut, they are spot on, i have just never got on that great with lining up. So today i have just gone back to what i have mainly used, Rubi's first one back is a TX700N. I will be selling my sigma's soon(ish) i have a 3DM and a 2C3.
