I have an older juicer that I dont think is made any more. Id does not get used much as it is a royal PITA to clean. It is the old type where the pulp gets slung outward and caught in the surrounding dish. The other problem is the spout height, too low for most cups or glasses requiring a shallow dish.
I would look for:
Ease of cleaning
Pulp ejection
A high enough discharge to put a reasonable container under it.
I have been eyeballing the Jack LaLane unit, but have not tried it. The unit you linked to looks more like a wheatgrass juicer, and looks like a lot of cleaning work.
Hope this helps give you more to think about!
Jason
