When I was a post-doc at Caltech, we used a mini-prep robot made a company
AutoGen.  It would do up to 160 3 ml minipreps. Normally, during the day,
we would limit it to 80 preps so that it would be done by the end of the
day.  The 160 preps would go overnight.  Recovered DNA was OK for
automated sequencing and other routine mol biol applications.  I never
tried it for transfection.  

If you want more info I can put you in touch with someone there who uses
the robot.
