I bought a master set of Geohex somewhere in the mid-nineties, along with a mountain set. It was a major purchase at the time, and we used it extensively. However, I always felt the tiles were a bit too large to be flexible, and were also fragile, made of styrofoam.
Somewhere in mid 00's, I switched to the Kallistra terrain system, which I still use, and which is much more durable.
But anyway, I sold the master set some time ago, but somehow never got rid of the mountains et. I still used the mountain set last february, in my 42mm game at Warcon. But now it is gone as well.
The Geohex era comes to an end!
