If you are going solely for figures and similar I would recommend that you get a basic liquitex, golden, etc set or similar and mix your own colours.
Most of the figure Modelers I know go this or a very similar route, there are a ton of skin-tone formulas out there and every modelers has his own favorite one.
Even if you bought paints loke modelmaster or similar you will still need to mix many shades for clothing, skin, etc.
