I like that idea of an electric igniter.  Wish I had had one.

Even the gun made me a bit nervous.  This stuff is really hot.  You do not
want it touching you during the "exciting" moment and it is always a pretty
'instant" (startling) moment when it ignites.  If your hand is in the wrong
place when it ignites, zero chance to escape undamaged.
