I would rather have an IFR GPS and an autopilot, than VOR/GS and DME
and an HSI.
But, heck, if you have the money, go ahead and get an HSI. You might
consider waiting until you have mastered the IFR GPS. Also, one REALLY
NICE thing about an HSI is most are slaved. No more worrying about
your DG accuracy when ATC gives you vectors. Nonslaved not quite as
satisfying. Slaved ones are $$$.

The autopilot is really nice on long trips, IFR or VFR and, if a
totally electric autopilot, a real safety device in IMC. They are
expensive and need maintenance though.

My partners and I are faced with a decision. What would you do?

We plan to update our outdated panel with a GNS480. The CDIs currently installed
are not compatible with the GNS480, so one of them will be replaced.

We could replace the existing CDI with a compatible one for $2000.

We could install a non-slaved NSD360 HSI instead for $3500.

If we install the HSI, the no-longer-used CDI hole can be used for the electric
AI that's been waaaay over on the other side of the panel.

I think I know what we will do (go for the HSI), but I'm collecting opinions.

Is the NSD360 likely to become a maintenance headache?

In the electronic age, does it make sense to install an electromechanical aid to
situational awareness?

Thanks,

Dave
