Bob Hunt recently said that balsa would become hard to get. I have found that it's not too hard to get, just stupid expensive. I just saw that National Balsa was selling a 1/6"x4"x36" for $4.33 a sheet. So, it's just horrendously expensive. Yikes. They do have the POS, heavier than a brick stuff for less. Guess I'm back to cruising the craft and sewing stores for wood.
Sigh....
