Cheap GPS Loggers for FAI Badges - Status?

Marc or others,

As I've dug deeper into this subject, the issue of geometric altitude
appears to be one of the true obstacles to the adoption of COTS units. Is
there a public record anywhere of specifically what objections the "members
of the IGC, or even GFAC" have raised? In doing just some basic research
(along with the help of a major instrument manufacturer) it became pretty
obvious that geometric altitude is the way to go at this stage.

My is opinion is (and has been for years) that the IGC should switch
over to using geometric altitude, which would allow use of GPS-derived
altitude with appropriate error bars. But, my opinion is not that of
the majority of members of the IGC, or even GFAC, at this point.

Suppose that one switches to "geometric altitude". What about people
who used to document their flights with barogaphs? Here all clubs have
barographs and lend them to the pilots when necessary. Hence the cost is
nil, which is certainly cheaper than the cheapest GPS.
