I purchased this, STEC were happy to provide an STC... But for $1500 US.. (jerks)... I have also found a Mid Continental turn coordinator for the system that uses the newer brushless design.
It still works out to be a "new old stock" and a turn coordinator that is "as new" for half the price of a new system.
I am leaving the install as the very last thing in case Garmin pull their fingers out with GFC500 certification for the 150/152 airframe.
