I have taken quite a few classes from Craftsy and loved them! Now to clarify, I have only taken machine quilting classes (not any piecing) and I have learned a ton. I have been fmq for many years and have difficulty in finding local classes to teach advanced techniques in fmq. Craftsy has filled that void. I highly recommend them and have purchased classes as gifts for my quilting friends.
I agree, wait for a sale. It's worth it!
