I don't know about Sig's financial health, all I know is I want to build a Seniorita but can't find a kit for anything!

One thing I can attest to is the vast increase in use of balsa for wind turbine blades. Right now there's a project going on about 30 minutes north of me that will ultimately see several hundred new wind turbines built. They're monsters, too. Huge blades, all with cores of balsa.
