I disagree. It'll pay for itself the first time your engine hiccups.
Mine paid for itself within the first 20 hours it was installed. I had
a situation (new engine) where the engine would get rough at the top of
the climb as soon as you pulled the throttle back. The engine monitor
showed that the #1 cylinder was going cold when that happened, which
pointed exactly where to look for the problem.

A year later, I had one cylinder that was suddenly getting lean too
quickly. The monitor told me exaclty where to look for an intake leak,
which was found within 10 minutes of pulling off the cowl.
