I have one site that I did pay for access to... abc teach It costs $35 a yesr or $60 for two years. It is full of printables. Everything is updated monthly. I love it.
abcteach did a free three month membership around the holidays. I enrolled for that time, but I wasn't impressed. To me the paid stuff was no nicer than the free stuff. That said, I was looking for K/1 things, so maybe upper grades' things are more worth it. The paid site I like is readingatoz.com. They have such well laid out, thorough lesson plans.
