On the far north side of town, probably Trip Davis' Old American and Tribute up in the Colony. A lower cost option might be Ridgeview Ranch, one of mine, off 121 but further up in Plano. Not sure if Jay Morrish's Castle Hills is private or public. Chase Oaks in Plano is also good (Von Hagge-Devlin)
Cowboys in Grapevine, one of mine, has won best public course about ten years running from Avid Golfer and is excellent in service and maintenance.
If mid cities, both Texas Rangers (North Arlington, John Colligan) and Texas Star (Euless, Kieth Foster, but only five miles or so from Rangers) are very good.
For the south, yes Cedar Crest (DA Weibring redo of a Tillie) is decent, as is Colligan's other renovation of Stevens Park (very short though) Way south, in Cedar Hill, my Tangleridge is under rated and reasonably priced (although was once ranked the 47th best muni by Golf Week.)
There are probably many more that I am forgetting this morning but among the publics, those stand out to me. Since you implied a stay in Dallas, I am leaving out many on the Ft. Worth Side.
