I've signed up for a bunch. Just signed up a for Angela's feather class. I really like the quilting classes and have learned lots of tips and tricks even in the more basic ones. I have a HQ SS 16 midarm sitdown, but even enjoyed the long arm ones - The ruler one especially. I think rulers are easier on sit-downs and it was all totally applicable to a domestic machine. I've never paid full price, but when they go on sale I keep picking up a bunch (sewing, quilting, and knitting), so I always have something to watch.
What's really nice is they now have an app for the iPad and iPhone, well if you have AppleTV you can then throw it up on your TV, which I do in my sewing room.
I'm like some of the others too. I like to watch, but don't do all the projects. I like to apply the techniques to things I'm already working on.
