There are three copies of "Classic Go Game-Set" at Barnes & Noble. It's very hard to tell the size, but it appears to be maybe 14-15 inch folding board/case and plastic stones. If so, it's not quite full size, but it appears better than the 12 inch boards out there. It's a full 19x19, so you can play a standard game. Just in time for Thanksgiving holidays with the family!
Here's a link to the game at barnesandnoble.com
for more information and a look at what's inside.
