I don't juice as much as I used to, but my thrift shop acquired (I think for $4.00 or so) Jack LaLane Power Juicer still works like a charm after almost 4 years of having it and using it much more often than I ever anticipated.
I have to mix the greens with the chunks of veggies to have them juice better than trying to stick noting but greens in, as it sometimes shuts it off and I have to open it, clean them off and start over, and watermelon rind was a bit too much for it unless chopped up super small. Otherwise, I never had a problem with it.
I juice the fruit and ginger root first, then save the pulp in a bowl, then juice the veggies and turmeric root next and save that pulp separately and make more goodies like crackers, flat breads, falafel, cookies, muffins, etc. so that nothing goes to waste.
When in a hurry, or not feeling like baking and such, the pulp can be frozen to use later, or can go to the compost pile which in turn helps us grow more goodies next year.
