The main thing I can think of that makes a DMM especially useful if you
have to troubleshoot an Elecraft radio (or nay other radio) is to make
sure that its input resistance on the DC Volts ranges is 10 megohms. 
Then you can be sure that a simple RF probe you build for the meter (such
as the one described in the K2 manual - and for which the parts are
supplied with the kit) will yield reasonably accurate readings when used
with the DMM.  Many inexpensive DMMs do not meet this requirement and the
resultant readings are perhaps only 10% of the actual signal voltage.

If I recall correctly, some of the alignment steps for the K2 require
using the RF probe with your DMM to measure small signal levels.

A PC interface is nice, but not essential.
