Hi. I wanted to buy a juicer, but I need advice on what kind to get. I'll be juicing a lot of tough foods like carrots and celery and watermelon rinds, so I need a machine that can handle all of that. I bought a cheap machine at a discount store, but it was such a hassle to chop my veggies into teeny tiny pieces to get them to fit into the machine and the machine's motor didn't have very much power at all. Also, I'm a college student, so I don't have a lot of money. Does anyone have any suggestions?
