Default Cheap electronic altimeter

Hi ya'll,

I need to replace my Van's (falcon?) altimeter. It has been slowly dying - I've been needing to frequently recalibrate it to keep it matching my spot on Dynon D10A.

I'm a little out of touch with the current market for 3 1/8" instruments. Before I just buy another altimeter from Van's does anyone have recommendations on a not super expensive replacement that could provide more functionality?

My requirements:
  • I don't fly IFR but I'd like to learn at some point. I originally decided on steam gauge VS+airspeed+altimeter as alternative/backups for the D10A and I've been happy with them.
  • That said, I'd consider replacing all three of my steam gauges with a single electronic instrument if it wasn't too expensive.
  • My D10A has an internal battery backup, but if I replaced my steam gauges it would be extra cool if the replacement also had backup power.
  • I have an altrack + pictorial pilot from TruTrak so I already have a basic 2 axis autopilot.

So, does anyone have recommendations on options? I'm hoping some current builder has been carefully monitoring the options and might give me some ideas.

Check out the Gemini mini EFIS. I would already own one if it had a RMI mode like the Dynon D10. As soon as they add that option out comes my old electric turn and bank and in goes the Gemini.

I would stick to the mechanical gauges as backup instruments, a backup battery does does not resolve all electrical issues. Maybe I'm just old fashoned but I just like to keep things simple.
