Where I used to work, we had both an Eagle and a CDC9766;  no problems
at all with the Eagle (in two years), but the 9766 has head crashed at
least once a year for the past five.  Not only is the Eagle more reliable,
it's smaller, quieter, cooler, and burns less power.  I'll take one over a
tank any day.
