frequency counter

As the title states, I'm interested in a device that I can adjust the range on the proximity for detection. I was sad to hear the sds150 will not be addressing this, but also glad that I cant justify the price because of this. To put it simply, I would like to extend the range of nearby...

I love my venerable MFJ-9420 except for the analog dial frequency readout, which is far from accurate. Does anyone make a decent frequency counter/digital display for these little radios? I can cobble something together, true, but I'd rather have something more polished and professional...
