AAA has some flights out of DTW that are great, I didn't look at a wide range of dates but here is one example:

$369
Economy Select American Airlines
1/25/2012 AA DTW 6:35a BZE 2:25p 8h 50m 1

2/8/2012 AA BZE 12:15p DTW 10:45p 9h 30m 1

I'll bet if you looked around a bit you could find some deals on dates that would work for you.

I've already told you more than I know.
