Lighting-kit choice is a question that faces everyone - except those who choose to shoot only with natural light. And, many have gone through several kits before arriving at something that works for them - essentially, wasting a lot of money along the way (even though the interim solutions seemed economical at the time of purchase).
Tungsten lights can be inexpensive, but tend not to be very practical for people work. Once you get enough light that enables you to shoot at reasonable exposures, the light is too intense for people to open their eyes, and their skin starts to darken, crack and peel.
Thus, my suggestion would be really give some thought to what you shoot, and how you want to shoot it (e.g. at what apertures, with which light modifiers, etc.), before taking the plunge. Then, decide on a product line with which you can grow over time as the budget allows.
