I really enjoy my K2/100.  I use it weekly for CWT’s, MST’s & SST’s with N1MM+. 
 I usually operate the tests barefoot but sometimes run a KPA1500 with the K2.

The shift/width controls are not as versatile as my K3S but I don’t need em for 
the 1 hr CW tests.  Computer control of the K2 and K3s is essentially the same.

I built the K2/100 myself and, as Wayne said, there is some additional 
fulfillment when using a radio that you assembled yourself.
