I'm going to go off in the opposite direction and say that small apple presses are labour intensive and are of exceedingly low productivity - ie a waste of time
I borrowed and tried one, and saw another in operation and they were both the same.
I bought a large electric fruit juicer off the internet (~£80) and found it far more productive, both in extracting the juice and in speed of operation. The pulp was really quite dry, the process was quick and the juice excellent. OK- not so romantic but then why waste so much ?
