The best pressing juicer would be the walker press.A hydrolic press with a chopper atachment,very heavy and way expensive.The next best thing is a juicer using triturating twin gear action for extraction.The gs3000 is a very good model for juiceing.I am unaware of a nonbias databank on the info. you seek about stage 2 juice.But as far as enzyme depletion goes on blending fresh produce.As long as you keep the temp. down along with the blend time its not a problem.I use water from the fridge and the produce as well.then I through in 2 ice cubes before the main blending cycle.The smoothie comes out well chilled.On the other end of the spectrum,you can cook with a highpower blender.Put in hot water add soup ingredients run until steam starts coming out the lid.3min.soup fast and easy,cleanup takes about 3-5min.Im using an older 2hp. model today there are 3hp. and 3+hp. models available.The more powerfull models require less blend time,cant wait to get one for myself.May we all be blessd with vibrant health,and happy holidays to everyone!
