If you're looking for low priced software that runs on mac and has powerful character animation tools, you could look at Animation:Master. Of course, from what I understand, it runs better on PC than a mac. You may want to look in the OSX section of the Hash Forums for any issues that might affect you. And netrendering for A:M isn't free, however they will let you use the cd to run separate instances of a:m on your different computers, so as long as you don't mind each computer rendering a different section of your animation, instead of all of them working on the same section at once, then there's no problem...
