When I was shooting out west earlier this year,in Death Valley, I ran into Chuck Farmer and a workshop group of his. I didn't do any of the workshop stuff, although I did attend a quick demo of polaroid transfers, but I can say from the dinners I attended with them that everyone appeared to be quite pleased with the workshop. Charles Farmer is a very capable photographer and from what I could surmise gives a very good and enjoyable workshop.

I think one of the keys to a good workshop is not just the choice of the photographer giving the workshop but the location as well.
