Applied Engineering also sells a power supply for the ][+ & //e
computers.  It is suppose to be better designed and extra heavy
duty.  Some of the problems people were having with AE's speed up
card was directly related to the week power supply of the Apple
computers.

I have seen two computers which were on in a lab, one with a Name
brand system saver and the other without any surge protector.
They were used for unattended data acquisition so they were often
on during thunder storms.  During one particular storm the power
line they were plugged into took a lightning hit.  The computer
without any protection had to have the mother board replaced as
well as a couple of cards.  The one with the system saver had to
have the system saver replaced and that was all.  No one can
really say that it was the system saver that saved the computer
of if it was just the randomness of lightning but the extra
$100.00 (actually less than that) seems worth it to me.
