OLC does not require expensive IGC-approved loggers.
Garmin GPSMAP 76S on eBay, ~$200 or less.
Besides, your club can use the help.

The Garmin is only good for the classic, not the triangles
or club comp. It would be nice if we could all agree
that the Garmins etc. could be used for the weekend
club thingy. However it will show what your score would
have been. Last time I flew I had a speed of 124 km/hr
which would have been a big help for my club. In the
first two rounds only myself and another tin can with
a Garmin flew so we got zero points.

Sorry you feel the badge thing is such a problem. I
feel it was fun to do things the old way and get my
badge with photos and signatures. It gives me something
to talk about with the old timers. I don’t subscribe
to any other gizmos and don’t even have a battery in
the glider, but the Garmin is great fun to see were
you have been and very handy to see the glide ratio
to the next airport.
