I've been working on moving this to this. It's got a bit of a learning curve, but I would say it's like Rails for designers with a GUI. That's not a bad thing. The bad thing is that it uses XSLT 1.0. Which is the least powerful language ever written (spec was written 8 years ago). It's not a procedural language, and if you don't treat it as one, you'll be ok.
Some posts about tutorials will follow.
