I'm currently flying VFR in a vfr equipped plane. What would be the lowest

flying?


Maybe something in the Apollo GX50/55/60/65 series? You'll find, though, that
the cost of installation is a big part of making it IFR, so if you're going to
spend a lot on installation, it seems a shame to waste it on a cheap unit.

I went through this calculation way back in 2000 or so. I even had the advantage
of having a loran that would have had an upgradable pinout to the Apollo.
I went 430 and am happy with that decision. I doubt it would have saved any
real money in any case.
