I just went on to the Drum Rocker website because I am interested in this cool product.  It says the drums can be played as an electronic kit but doesn't say if the brain thing is included with the kit itself.  For $300, I would expect it to come with the thing, but sometimes they get ya.  Anyone know the real story?

Hm, well I read some of the comments on this page (use ctrl + F and search for "brain"):

It sounds like you have to buy a brain separately.

Actually, I just checked the website and it looks like the module might be separate.  Even worse, the drum module costs upwards of $300 additionally!  That is total bullshit and goes against the "gamer to drummer" vibe the set has been going for.  I don't think anyone will honestly buy an addon that expensive for a game controller.  Hopefully something will change in the meantime making the drum set cheaper.  

Yep, the module is separate. You're looking at upwards of $900 with the module, and some extras.

for $900 I could buy some awesome, quality REAL drums! probobly with a shitload of cymbals, too... and like, 5 tom-toms

Thats the price of electric drumkits I'm afraid.

Yeah, pretty standard fare.
