There's a version of the Enneagram test (as well as other personality tests) available here: http://similarminds.com/personality_tests.html
Admittedly these tests aren't as accurate as the ones you pay to take, but interesting nonetheless! After a workshop on the Enneagram, I know I'm a type 9 but this test had me as either a type 5 or a type 9. (They do share some similarities).
So: Are you an Achiever? A Loyalist? An Enthusiast? A Peacemaker?
