However, before I’d go off and buy a particular drum kit I’d be sure to do your research (a quick Google search already turns up some complaints at the unofficial Roland V-Drums forum, such as this one).

Why an electronic drum kit? The first article on Google for the search query “advantages of an electronic drum” sums it up perfectly:

In the acoustic drum world, there is no such thing as a quiet drum set. Drums are meant to be loud, and if they are played quietly the sound just isn’t right. [...] But electronic drums can be played as quietly as you like. Just turn down the volume control.

Basically the only sound that is made is from the sticks hitting the pads.

Awesome.
