This should be said: Techno is a lot bigger than Berlin-minimal, and one could remain a Techno DJ and never touch a track from Richie or Magda's USB drive. There are many DJs -- Claude Young, Dan Bell, Rob Hood, Buzz Goree, Ken & Karl Meier, Alan Oldham, Mike Huckaby come immediately to mind -- who stay more on the techno side of the fence and still manage to do interesting, dynamic, butt-moving sets.
And of course, all of the people mentioned above will drop a house record if it fits what they're doing.
