Try sailor-6219 on ebay. I bought 10 sets of tight grained, quartersawn ADK spruce from them. I then sold 5 sets on ebay and made most of my money back. I just finished a uke with one of the sets and I'm very happy with the tone and appearance. See the Act of Selfless Generosity thread for photos.
I have a ton of it. I picked it up off a local guy that sells tops to Martin Guitar. I buy the short and narrow pieces that he can't use which seem perfect for ukes and my octave mandolins. I've been planning on having a wood garage sale and hope to have some lots listed on my site in the next two weeks. If you're interested in something let me know. I normally don't sell tonewood but have decided to sell off some inventory to fund more exotics.
