Yup, the screw is better, but I think that's why all those small presses (e.g., Sundhara and TŠby) are so expensive. That screw is a fancy piece of work, with the outward taper at the end to increase the pressure, and the periodic gaps along the thread (???......maybe to help stir up the seed cake?) That's why Bielenberg's press is so popular in Africa -- it's CHEEEP!
