I totally agree.
As far as turning the key I love to tell my students that Hughes came up with the idea of a starter button back in the 50's and that my car sales person was trying to convince that starting the car by simply pushing a button was something new ;-)
We've never had any problems with firing up one of our fuel injectors (neither on the 300 C nor on the Raven II, neither at -10°C nor at +30°C). However I see our competitors flooding their carb equipped ones every now and then, specially in winter time.
Maybe the Diesel modified and installed in several airplanes by a company called "Thielert" would have been a good alternate for the Guimbal. (I think it's a modified CDI 190 taken from the Mercedes A Class)
