As asked by someone, where in Dallas are you trying to go? This can affect your airport choice.
KADS is okay for much of the northside, but it is expensive to operate out of. A decent alternative is Dallas Love (KDAL) and sing the Business Jet Center FBO in the NE Corner. Andrew Finne (ARflyer here) has been there occasionally with his commercial students.
The other choices:
