I've bought balsa from both Lonestar and National balsa. National's quality is somewhat spotty IMHO, one order the wood looks great, the next the wood looks like crap. I've been very happy with Lonestar, Mike was able to fill a rather large order for contest balsa that several other suppliers simply couldn't fill. All the balsa looked great and was very well packed. They will also custom cut wood for you if you need a size that is not listed.
