Then
the buyers will pay maybe 1k to 2k over the price of the plane without
that 430 in it.



Uh, I think the point is whether a buyer will consider the plane at all,
no matter the price.

And as a hint: you might just want to consider those anger control
pills...



I am still trying to figure out why buyers enter into the whole
conversation at all. The OP never made andy statements about selling,
nor did he say he wanted a GPS.

It is undisputed that owners will never recoup the cost of installation.
So, again, why the heck would you put one in just to make it
attractive to buyers?

Anger management pills? Who's angry?
