Drum Machines

[steelcmg]

So my cousin and a few guys are into playing death metal and are having a hard time finding someone to play drums for them. So they where thinking about getting a drum machine. He asked me to see if I could find out some info about them but I know nothing about them. So for any of you music buffs out there what should I be looking for that can handle playing double bass type beats realllllllllllly fast or can all drum machines handle things like this. Links would be really helpful.

Since they probably want something inexpensive, the best drum machine in its price range would be this. (http://www.sweetwater.com/store/detail/SR16/)
