Chuck does make a very nice uke and they are hard to come by. As noted, he does not have a public build list. He usually sells through The Ukulele Site, which auctions them.
Here is mine, which I bought from the original owner:

Other builders who you can actually commission a uke from that are every bit as worthy: Jake Maclay (Hive Ukuleles), John S. Kinnard (Kinnard Ukes), Joji Yoshida, Beau Hannam, Jay Lichty and Steve Grimes.
