I remember purchasing a radar detector around 1986 that performed better than my escort (or any other detector I had - whistler, cobra...). They were located in a suburb of Dallas (on the east side of Dallas as I remember). I am just trying to remember the name. I actually visited their location in Dallas and had them check out the detector - which they replaced on the spot (I think it was overheating and shutting off). I remember how friendly and helpful they were.
Let me know if this rings a bell for any of you.
