For the price of the Basic Package of BIAB one can purchase Logic Pro app from Apple. Its $199. Comes gigabytes and gigabytes of sounds, a plethora of synthesizers, and a good cross section of "drummers" in varying styles with varying kits with highly customizable grooves. Plus its a full on professional recording platform.

I can understand the desire to take the easy way of pre-made style vibes, but for the cost you can't beat Logic.
