This is the one I have. I bought it years ago and use it often. The reason I suggest this one is it comes with everything you see in the photos. I am still working on the box of ready made bobbins. I save them when emptied and put the matching color of thread I am using on a project like making lace items.
It seems like a lot of money upfront but everything you need to get started is all in one box.
