hey... my daughter has one of those duck quacker gizmos!
welcome. I'm a newbie too. I have an old braun juicer which works beautifully but I bought the breville plus for $120 it was an usually good sale as it is normally $199. I really like the wide mouth so you don't have to cut fruits and veggies as much and tall pitcher so you can make a lot of juice at once without having to stop the machine to clean it for the next batch.
As for any kind of advice... I just read and read and read the discussions and posts. start with the Tracker.... the third link under your Inbox and explore that. It even gives you advice & encouragement as you log in your daily progress. Nutrition-wise & and body symptoms-wise, I usually explore Discussion & use the search feature to find topics relevant to me. My fav juice is carrot, beet, apple, ginger, lemon.
