When your ready to take juicing to the highest level,get a masticating juicer.Ive had6 centrifical juicers over the last 15 years.But once I used a masticatng juicer I new I had found a superior juicer.The quality of the juice is difficult to explain,you have to try it for yourself.I have a single auger model and a dual gear model they are both very good juicers.I wouldnt recomend a hand cranked model,unless you have good arm strength.But it would be an enexpensive way to get wheatgrass juice.Check out happyjuicer.com they have reviews of juicers and they dont sell juicers!I purchased my juicers at vitalityplus1.com,good prices and they ship from the midwest and west coast.The most efficiant juicers are the twin gear,also considered heavy duty.
