Solved:...
went with a zoji boiler.
So.. I've had too many die on me, 6 in the past 10 years. Daily use, sometimes twice a day.
It seems the most typical point of failure is the solder point in the base, where the power-cord joins the copper contacts that extend INTO the removable top kettle.
Looking at the designs on amazon, it would seeeem like some oem in china makes ALL of the kettles...
Thoughts ? go stove top ?
