We have the Juiceman which is very good. We've had it for years and it works great.
My husband wants the Jack LaLanne deluxe juicer. From what he tells me, you can toss the fruits/veggies that you're going to juice into the chute whole rather than cutting them up and that it uses almost everything in the food and cleanup is much easier. I wouldn't think you could put a pineapple in there whole, though. LOL!
There are 2 Jack LaLanne models... one is $99 and the other is $199. It's the $199 one he wants, so he'll be waiting quite a while for it. I can't remember how much the Juiceman was, but I know you can get both the Juiceman and the Jack LaLanne one at Target.
