There is also the LXNav Air Data Indicator - combined altimeter and ASI.

With either of these devices, is there any battery backup? Is there a legal requirement for a battery independent system? Do you have to have any instrumentation separate from the flight computer since flight computers can display all of altitude/height, airspeed and vario, and can control radio and transponder?

LXNav states clearly that it is not certified. What a waste of panel space then.

Experimentally licensed gliders should be able to use it, right?

You did not say what kind of altimeter you have?

It's a Falcon ALT20INF-3, http://www.falcongauge.com/xinjia/ALT20INF-3.jpg

Replace it with a...!

I love the idea of some of these products, but I'd rather redo the entire panel all at once so that I can optimize for space, ergonomics, and redundancy. If I can make this altimeter work just a little more smoothly it would buy me some valuable time.

Here is one place that rebuilds altimeters:

Not sure if rebuilding includes certification (it should).

Personally, I would switch to electronic if I were you. I have a Garmin G5 in my glider and I love the smooth response; you can even use it as a vario.

This replaces about 5 other instruments at a very reasonable cost.
