where are the 4x4 / offroad shops in Dallas?

I see a lot of 4wds and Jeeps on the road. Where are all the 4wd shops? There are times when I want or need to get something right then instead of waiting on mail order. I only know of 2 and they don't always have what I'm looking for (not that there's anything wrong with these, just looking for options).

In Plano there's:

All Terrain Fabrication
4 Wheel Parts

There's got to be more than those 2. Post up what you know!
