The Guild homepage has a link to photos from a recent article written by Will Beemer covering a Heartwood class project.
While I have never taken a workshop on basic timberframing, my opinion is that you would learn more from a school with education as its goal (Heartwood) than a company with profit as its goal. (I know if we put on a workshop it would be very different than Will's program at Heartwood because our goals would be different.)
Good Luck,
