I just got my author copies of the Sybex book for exam 70-444 and have to say the book looks good! I wrote the SSIS chapter and it is amazing what a couple good editors can do to make it really look professional.

I've enjoyed the simpler rules and spontaneity of publishing content on SSC for years and I had been reluctant to make the time commitment even a chapter requires. This project came to me via my friend Steve who was asked to do a couple chapters and thought it would be a good learning experience for me (and it was). The editing process was rigorous, but not unbearable, and it was easy to see how the final product would benefit. I had to learn their formatting rules which made the writing just a little harder than it would have been otherwise, but maybe the most challenging and most fun was figuring out just what to put in or leave out to support the objectives. I wrote about 90% of the chapter, then went over to take the exam to make sure I wasn't too far from what MS in mind. Passed the exam decently, and as expected the SSIS questions were very high level.

I haven't looked at the other 70-444 books to tell you if this one is better or worse than the others, but if you want to take a look anyway it's available at Amazon.
