I tried QNN for a year and lost interest in it so I didn't renew. I joined TQS when they had a special and I really enjoy it. I have also done the Missouri Star classes (2 of them) when they were on sale. They are not earthshaking, but I like the review of techniques and quick ideas. The free videos on utube are often super as well. It's all dependent on time and what money is available, I guess. :-D
