Get a Rotovibe

Save then. Buying sub par equipment because you can't save for another month or two is ridiculous. Make deals with your parents to rake the leaves or something for a couple bucks. Before you know it, you'll have enough to get something that you'll be happy with rather than something that will just aggravate you when it doesn't do what you want.
