Draw a big line from north to south through DFW airport.
Pretty much everything east of the line that doesn't suck will be overpriced.
Better luck west of the line.
I did the apartment scout thing a year ago... avoid Arlington and Grand Prairie, and southern parts of Ft Worth and Dallas both.
Stay out of north Dallas and Plano/Frisco area. Unless you're flying big iron for Suthernjets Innanashunal, you don't wanna play there. The areas NW of Dallas in between DAL and DFW aren't bad.
Will you still be living on the back side of the clock? Commute time in the DFW area is a BIG factor in where you wanna live.
Some places you just don't wanna be during rush hour.
On the LBJ Expressway, Friday night rush hour starts Thursday afternoon.
