miriam, the name of my juicer is The Miracle Juicer, made by a company in Poland. It's really a very good juicer and has a 3 year warranty. I just found it on the net and one company is selling it for $95 (I paid $125 for mine 3 or 4 years ago). I guess the price has gone down because juicing is no longer the rage it was then.
Now you've got me interested in juicing again

I think I will just have a glass or two a day, instead of trying to drink several glasses a day the way I was doing. I think that's why I got burned out on the work it involved with trying to make that much juice everyday.
As to being able to cut out your vitamin supplements, unless you are drinking several glasses a day, with lots of variety of vegetables and fruits, you will still need to supplement. But you should be able to cut back on the supplements. Good luck, hope you like juicing, and thanks for getting me interested in it again!
