I'll agree that the R-390 or the A version are about the best.
For general coverage, consider an R-392. Doesn't have all
of the bells and whistles of the 390/A, but basically the same
rig, far cheaper. Of course, as others have pointed out, no product
detector.

Another possibility is a Halli SX-117, which does have true SSB.
Its primarily a ham band receiver, but with an external synthesizer
in place of the LO xtals, it works fine as a general coverage
rig. Restored one recently, and its performance is impressive.
It will haul in signals my TS-830 will not.
