I'm considering juicing
Juicing is by far the best.
The only problem is that you have to continuously buy fresh fruits and vegetables.
If you are cheap, juicers can often be found at yard sales. Look for a larger "mouth/throat" and remember that the ongoing problem is the difficulty in cleaning the damn thing, which has to be done right away and is a pain in the ass.
My Juiceman II is only a mediocre juicer, but it is the one I use most often because I find it the easiest to clean. I have a couple of others, including a Jack LaLanne, which are much better but harder to clean.
Or, best of all, get an over-powered blender and buzz the entire thing down to mush.
