Never actually got the chance to rent in the area, but did manage to scout a bunch of FBOs out at Addisson, TX. It's about 10 miles NE of DFW just off the North Tollway.
There are a number of FBOs at the field, but they are not all located in the same place, Monarch, Flightline and Classic were the places I found there, there are more!
Also a good flight museum on the field if you are into that sort of thing.
Enjoy
