If the GS head is your only one, then it has to be new... If you have a
backup, then overhaul is OK - in your case it is not capable of an OH and
you don't have a backup GS, so moot point...
On the airspeed, I personally would replace it with new, but since a non
functioning airspeed won't kill you, overhaul is an option...


Dennis,
I tend to agree with you. My experience, as well as the experience of
my avionics person (who's also a friend of mine) is that the overhauls
don't tend to last as long as new. I'm not sure why you're statement is
causing so much heartburn. Afterall, everyone can make up their minds for
themselves. I'm not sure I'd worry as much about a GS head as you, but
I don't really fly much IFR anymore. After going through a few overhauled
AI's, I bought a new one and it's been great for years. I'd probably be
tempted with getting my DG overhauled, since the compass is a backup in an
emergency.
