I did this once years ago and got INTJ. I'm not sure that I trust the test, though, because some of the questions have 'right' and 'wrong' answers, or else answers where one answer is preferable in the sense that you might lie on a question to avoid a character flaw. (or at least on the version I did it was like that) However, based on the personality descriptions, INTJ does probably fit me best. After this morning's tournament I might retake it and get some hard numbers and see if it's changed :p
edit: tourney cancelled due to server failure so...
INTJ
Introvert(56%) iNtuitive(50%) Thinking(38%) Judging(44%)
•You have moderate preference of Introversion over Extraversion (56%)
•You have moderate preference of Intuition over Sensing (50%)
•You have moderate preference of Thinking over Feeling (38%)
•You have moderate preference of Judging over Perceiving (44%)
And yes, some of these questions had biases as I mentioned above, so it may not be fully accurate for some.
