I asked this question a couple of years ago and purchased a refurb 8500 from Escort for my wife's car. It was good for a while, but then started going into self cal mode more and more frequently. Now, it's to the point where it's unbearable.
I don't want this one repaired and I don't want another Escort. Are there any other RD's in the sub $150 range that are a good value? The only requirements I have are:
1) decent Ka sensitivity
2) must be able to disable X-band
3) must have phone style power cord so I can mount up my V1 when I drive the car.
