Just start with what you have. There's no need to spend a lot of money up front on this. A big part of the primal lifestyle is keeping things simple. Over time, you will dial in more closely both in terms of the quality of food you eat and the utensils you use to cook them. The main thing is just to start eating more vegetables, fruit, and meat and cut out the grains and sugar. That will be plenty enough for right now. Best wishes!
