I'm a heavy user of DGEAR in my research.  It will use either 12th order
Adams predictor-corrector methods or Gear's method for stiff equations.
So far, it's been very reliable and moderately fast.  It's certainly
faster than Runge-Kutta and other similar methods.

DGEAR is part of the IMSL package so it's not cheap.  Check with your
organization's computing center with the hopes that they will foot
the bill.
