Paul,

I can't see that WAAS is not here to stay. But the 430/530 will support
WAAS, too.

Some dislike the operating of the CNX-80 and find it more convoluted
than the 430/530. Some love the CNX-80 for the ability to enter airways
in flightplans.

It is pressure altitude and the 5 times per second GPS engine that give the
CNX it's advantages.
