help choosing the type and brand of paint to use for my kitchen

[scotchnrocks]

I'm painting my kitchen red this weekend, and I don't know anything about painting walls in a house except to mask off the area you're working on and stir the paint really well.

What is a good type of paint and brand to use with a limit of $40/gallon? My kitchen is rather small and has sheet rock walls that are already painted a medium tan color.
