IMHO, get a mechanical back-up!!!  Having been in an airplane during periods of high static build up, I have seen every screen on the panel go blank and reboot.  A stand-by attitude indicator is a completely different technology making it a true back up.  (it's also more reliable than any glass EFIS by order of magnitude)

I have a Mid-Continent "Lifesaver" gyro and am very happy with it. Micah Froese

I will certainly check into this.  But the problem brought up a
limitation to my panel - lack of ADHRS redundancy.  I started shopping
and found that a second Pinpoint might cost $17k whilst a
new-and-improved Crossbow 425 is about $3k.  I'm now considering the
current Pinpoint running screens 1 an 3 and the Crossbow feeding screen
2. (after we have traced down the current problem naturally).  Thoughts?
