Real Techniques brushes are as good as the drugstore can get!  These soft brushes apply makeup smoothly and give an airbrushed effect.  These colorful brushes are affordable if you are on a budget, You will get great quality for an amazing price.  My favorite brush is the setting brush it is great for applying a setting powder over concealer and works great for countering and highlighting.  The deluxe crease brush is great for blending out under eye concealer to give a airbrushed effect. http://realtechniques.com
