I am interested to know if anyone has attended stock specific photography workshops, and have recommendations for ones that made a big difference for them.  I see Bryan Peterson (Understanding Exposure) does several workshops per year.  They range from $600-$1200 for U.S. based workshops, with the more expensive ones including models. 

Anyone have thoughts on ones they have attended, or would like to attend?

I took Bryan Peterson's online class through PPSOP for stock photography which cost me $2K.  Although I gathered a lot of useful information, I do not think it was worth $2K and in the end was disappointed. At the time PPSOP was somewhat new and Bryan seemed to be quite distracted.  Between problems with the site, administering the class, and traveling for shoots, Bryan seemed to be gone more than he was around.  I had heard he's a very good instructor which is one reason I chose to fork over the $2K.  However, I did not get to see that.

Many things have changed since then with PPSOP for the better.  If Bryan has the time to devote to the class now, it might be worth it.  I think I'd much rather do a workshop though.  I don't learn as well online as I do with something "hands-on".
