Does anybody use these? Are they worth the few grand to buy one? I was thinking about getting one for the shop so we dont have to waste time rounding the dough and dividing it, but one thing I was thinking of is when we do mediums and smalls and boli's we only make 1 size of dough, large and just cut some off. Could these be salvaged? I realize dough is not the most expensive thing to make, but it could save us some time. Also, do these divide the dough by weight?
