The ones they use in houston are a laser, no radar involved. so you get caught every time. don't waste your money fighting, The judge will side with the officer.
HowStuffWorks "How does a laser speed gun work to measure a car's speed?"
+1 There is no such thing as a laser detector only a ticket detector. Think about the physics behind laser. It's a beam that is practically instantaneous (Speed of light anyone?) if they shot you they caught you simple as that.
Also I work for the DOT and I know from talking to some of the traffic signal guys that the freeways are now littered with radar emitters which completely throw off your sensor with the constant chirping. I took my radar off because I was tired of hearing it go off every time I ran by one of those emitters which operate in the K band. Nowadays X = doors, K = emitters, Ka or Ku are your best bet for radar but as 09 said Cops like laser better these days because of how they work.
Best way not to get a ticket is to not do anything that might land you one. Seriously though for a 30 minute trip at 80mph your time savings compared to traveling 65mph is only a matter of a handful of minutes in real world conditions. Why pay more in gas and huge fines for just minutes?
