High power zeners are nearly bulletproof when it comes to brief
overloads, power surges, spikes, arcs, etc, etc. Your low power
transistor-and-zener approach seems a bit risky by comparison. And if
you use a really high power, high voltage transistor, what have you
saved? Power zeners are pretty cheap anymore.
KISS is Murphy's worst enemy. :-)
