There are some non-TSO's EFIS systems around for under $2000! I saw
one at Oshkosh and was impressed! No moving parts, fully electronic.

You can also buy a solid stage gyro that feeds your IPAQ. If you use
AnywhereMap as your GPS already you can just switch modes. However,
having a dedicted instrument sounds like the best solution to me. I'm
probably going to postpone my traffic watch system in favor of the
electric AI.
