You could get 200 US glider pilots to chip in $500 on something that
won't increase their L/D? You must be quite a salesman 8^)

I for one, will be more than happy to chip in $500 for something that
will significantly increase safety. Most of us spend up to about $1000
on parachutes which we probably never use, so why not a Flarm like
device? I hope someone will either license the Flarm or produce
something similar, and then make it mandatory... Till then we will
continue average at least one mid air per year in the US...
