I took that class and I liked it. She does some amazing things using just a walking foot and I have used many of her techniques in some small pieces I have quilted. The price is certainly right and it will be a good chance for you to try out Craftsy to see if you like it. Go for it!
Also, remember that Craftsy will refund your money on any class you don't think is helpful. While it isn't like being in a classeroom with a live instructor, I have found the Craftsy classes to be very helpful.
