Most often, when I’m painting a model I use my sample pack of Rosco supersaturated paints.For somewhere around $50, I ordered this package that contains one ounce of every color they make in Rosco Super Sat. It's exactly the same as the scenic paint, just in little containers.
I own a lot of really expensive brushes, and for certain jobs they are perfect. Chip brushes, however, also have their uses. They are the cheapest brushes available.
