Hello Alek, I still dont know what form will have the stem, this could change price significantly. Materials are not much expensive, but it takes a lot of time to assemble the tube, pump it, fill it and so.. I am still in a phase of making prototypes, far from real production. But if everything will be ok, I guess the price of the z568m-like tube will be under $200.
