It seems Jack LaLanne is the winner!
Thanks for all your thoughtful replies.
It's easy to get bogged down with masticating vs. centrifuge, fast vs slow, top dollar vs. not out of my range, etc.
Actually, I'm using a $14 Hamilton Beach from Walmart. It's been in the family for at least 4 years, (not used heavily for all that time!) and it does the trick. It cleans easily enough, but I did notice pretty wet pulp, and that was bothering me. Veggies aren't cheap, and I wouldn't want to waste anything if I didn't have to.
I'm thinking about the Jack LaLanne, because the Green Power is just out of my range and I'm probably not going to be juicing 4 meals a day forever. I have a 14 year old Vitamix that I love, and I make the "whole" juice once per day.
But it all gets so confusing - heat vs not heat, pulp vs no pulp, it's enough to make one's head spin!
Needless to say, your insight is very much appreciated!
