I am planning the upgrade of a Piper Navajo panel. I wouldn't mind
spending the money for "cutting edge", but it is not clear what is
avialable and the infrastructure to support it. Could anyone provide
informed councel on EFIS or other certified options?
My questions are along the following:
1. Should I install Skywatch/Mode S or wait for ADS-B (I fly east
coast)?

Skywatch. Works everywhere, mode S does not.

2. Ditto on satellite weather?

Get the EX500 with datalink weather from Avidyne. It will show Skywatch
also.

3. Are any of the "economy" glass panels certified for retrofit?
I curently have a Garmin 530 and steam gauges.

A couple are. Look at Chelton and Meggitt / STEC.

Agree with all the above, but Meggitt is not yet or even planned for
certification for the Navajo. http://www.magic.aero/stc.html

The "soon to be released" Sandel SN3500.
