Cobra Class 4 premium with EPS is probably best for a variety of heavy-duty uses from leather bags to belts and sheaths. The basic Cobra Class 4 is $1000 cheaper and the mechanics of it are still great.
The Fabricator is great for sails and ok for leather, but it is not nearly as flexible as a cylinder arm machine which can be converted to a flatbed if needed. Our Necchi plastic sewing machines have the panel that comes off to reveal a sort-of cylinder bed which is really crucial for hemming pant legs and sleeves. A Cobra Class 4 would allow makers to create more leather clothing and 3D objects like complex bags. Ever had the zipper of a leather bag break? With a cylinder arm machine, you could replace the zipper without having to tear down the entire bag to get it under a flat bed.
