CORRECTION (OP has been edited for clarity)
Okay. Let me be clear. When I say killer performance I mean >6 1/2 digits, 0.0002 % accuracy, and drift in PPB....you know, the kind of features you find in a >$1k bench DMM
In a DMM I would like a nice set of features like capacitance, conductance, peak hold, diode measurement temperature, good clear display, backlight, low burden voltage, etc.
Something equivilent or competitive to a FLUKE 87 IV or V is what I seek
