Good references for ARIA use?

Question

Does anyone have any trusted references for ARIA use? I'm looking for something to base my markup on, but can't really find that many examples from trusted sources.

Right now I'm pretty much going from the ARIA spec and from this site, but would love a couple more good references to make sure I'm doing this correctly.
