the balsa wood is imported from elsewhere, but once it gets here it is subject to whatever laws the government decides to make or break to use it how they see fit. I don't think their vision matches mine (or hobby enthusiasts in general). The Gibson fiasco was also concerning imported material (Rosewood specifically). Many believe that the fines and siezures they experienced were due to payback for being a non-union right to work corporation. When I recently re-entered the hobby, I was having problems finding the Sig kits that you mention. With some patience and diligence, I was finally able to secure all of the kits I wanted and a backup for future use. As I said earlier, I have a total of 3 of the SE kits! I see the Sig supply seems to be getting better of late, but still seems to be listed as out of stock in many purchase sites. But I think they are also going thru management/ownership changes as well, so it may not all be due to the windmills. I hope they continue to be successful because I really like their products. The kits all build well, look good and perform. I recently got some more done with the thread topic plane and will take and post some photos soon.
