I'd forgotten how much I love sewing with my Monster (so named because I've moved house five times since buying him and I know what a monster he is to move). He's fast, accurate, responsive and just all out powerful. I guess he's my version of a hotted up power tool! LOL
My little Brother is a lot easier to use when I need to change thread colours frequently, and of course needed for anything other than straight sewing, but I'd fallen into the habit of always using the Brother because the chair was there and everything was ready to go.
I'm hoping to get back into some garment construction soon, so my Monster should be getting a bit of a workout! Maybe after that I'll be in the habit of using him for all my straight line sewing.
