Essential Elements Interactive - A Reason to Switch to EE?

I just discovered the amazingly wonderful teaching tool and student motivation greatness of Essential Elements Interactive.  It's basically like having a free version of smartmusic, except students can do multiple takes of a recording, and submit their favorite one, but without the green/red note instant feedback.

Watch the video from Steve Smith at Hal Leonard:

The video found HERE I find to be better at showing the awesomeness of this online tool.

Click the "EEI Quick Tour Video" button for the overview of all the great features.

The price tag of all this makes it the most impressive - FREE.  Well, free with the Essential Elements books anyway.  The only negative for me is that we are currently using "Traditions of Excellence" books, and I really enjoy the way the books are put together since we start with like-instrument classes.  The EE books do not have many of the great things I'm looking for when starting just horns for instance.  The Traditions of Excellence books use professional musicians to demonstrate in the DVD's, and EE method books seem to use kids.  Granted, they are teaching the concepts properly, but there is something about having an adult professional vs kids which helps to make the students believe them w/out questioning integrity.

Now I have a big dilemma... do I make the switch from ToE back to the ol' EE?  I used to use EE years back, and many of the guest teachers I would invite in would point out the flaws in the book.  I had no defense.  Then ToE came out, and I never looked back... until now!

This is going to take more research before I make a commitment, but the good news is that it is VERY easy to switch to a new method book anytime at my school.  

I would LOVE to hear your thoughts and comments on this!  Feel free to leave them below!
