Any FREE and EASY Mind-map software?

hi all,
I'm new to thinking through Mind-map software, especially as applies to story-boarding a novel. Ideally it would be EASY to use, and FREE for my old G5 10.5.8 as well. Any ideas? What would be best for mind-mapping a story? (Will import these graphical solutions into my Scrivener Research folders).

When I look at a list of software like this, I get a little overwhelmed and upset. What to do? Where to go? Who to trust? Which is a one-man-band that might retire and which is a more trustworthy and enduring team?

I think you missed the bit about it being free.
