Are there any painting clubs at your FLGS? Getting together with other painters might give you a chance to try different paints to see which you like best. Just because one painter likes a brand doesn\'t mean that it\'s a good brand for you.
Failing that, you can pick up a few pots from each brand that you want to try and go from there.
Which paints exactly depends on what you are painting and what you need. If you are painting orcs with a traditional greenish tint, you\'ll need some greens or olives, but may want to pass on the blues.
For example, pick up a skin tone triad (tanned?), Brown Liner, and another triad (off whites? ivories? bones?) from the Rear MSP line (or just get one of the Learn to Paint kits), some from the P3 line (I\'ve heard that the reds are good), and some from GW.
