George,

It's a common concern and I hear it all the time from Lyc owners. Since they 
don't understand it they don't trust it. Now a magneto...... Well everyone 
understands and trusts a magneto. For 500 hours. Then you better overhaul it 
because your on borrowed time after that.

Talk to any car owner under the age of 30 and mention a tune up. Most of 
them will look at you like your crazy. These days nobody thinks twice about 
driving 100,000 miles without ever doing anything but changing oil. Not even 
changing spark plugs. I remember my first car in high school. A 67 Camaro 
with a warmed over 396 and dual point distributor - hottest ignition going 
at the time. With a high perf coil I spent more time replacing, cleaning, 
filing, and adjusting points than I did driving the car.

Funny that in the example you cited it was the mechanical switch that got 
you, but you immediately went to the more reliable (no moving parts) 
electronic system as the source of the problem. I guess its just human 
nature to assume the worst (been there).

I've given up trying to explain the choices I've made in my airplane. People 
either get it and think its great (rarely), or they think I'm a dumb guy 
with a death wish. Whatever.
