I have taken lots of Craftsy classes, too. It's hard to pick a favorite because they are all so different! I loved the two from Jenny Doan. I also liked Wendy Butler Berns class.... guess we all have different opinions, but that's what makes the world interesting.
As others have said, it's really no risk to take a Craftsy class, because the people there are wonderful to deal with. They will happily change your enrollment to a different class if you find a particular teacher is not to your liking.
