I bought a LaLanne juicer for my wife (Christmas gift requested) a couple of years ago when they were cheap. (Think I got mine for like $79 or such plus shipping.) All the above observations are accurate (product use, cleaning, orange stain) and add to that you have all the "residue" to deal with. Like mentioned, that's where a lot of the good stuff still is, like much of the fiber and a lot of vitamins. We used to save some of it and use it in salads, but it has no taste at that point. We had rabbits at the time that loved that junk, but I don't have them anymore. Composting the resdue seems like such a waste to me! The juicer sits on the shelf now - maybe I should just sell it.
Bottom line: Juice tastes great, not worth the expense and effort.
Another consideration, something I've only learned recently: It's not just what you eat but how you eat it that's important. If you're overweight like I am and thus at higher risk for Type II diabetes, vegetable and fruit juices are a no-no. It's not the calories, but the glycemic index at play here. A carrot eaten as a carrot has the same calories as the juice it produces, but is much lower in GI than one that's juiced. The sugars/carbs in the highly processed juice, which the body can then assimilate much quicker, result in an insulin spike, leading to greater hunger, more calorie consumption, greater weight, etc. It's part of the viscious cycle. Much better for folks like me to just eat the carrot and let my body do the processing...
