Even the IN-13, with the extra "hold down" cathode, has problems after 
running continuously over a long period.  One of my friends bought one of 
those kits, were the glow just grows, and shrinks, alternately. Its still 
working after about a couple of years. But in less than a year, it would no 
longer lock at one end, as its suppose to. The glow center, now sort of 
drifts toward the middle. It now grows and shrinks outward in both 
directions. Kinda cool, if you didn't know, how it was intended to work.
