GH,
Unfortunately it is a very different world from when Carl owned Semroc.
Balsa prices have quadrupled and what is available is often really poor quality.
Tube quality available from the former Euclid has gotten so bad that much of what is being produced is unusable, even though the cost has gone WAY up.
Semroc has discontinued a huge number of kits and all but a very few, like the Mars Lander, will probably go away soon.
At current prices and quality, Randy is finding it VERY difficult to keep producing the line.
Wish it weren't so, but it is.
