I know off topic, but there are quite a few drummers here too. Have you seen the Roland V-Drum Lite electronic kit? Pretty interesting kit. However, take a close look at the position of the sound module itself..... Now ask youself this.., does this position increase or decrease the life expectancy of that module? If you ask me, they couldn't have put that module in a worse place. I "predict" many "unintended" hits to be taken by the module due to its location.
