It really depends on how you think your memory. If you are scared by
such universal inerference, then the money is worth. I would believe
my configuration that give me very safety boxes. 50 CPUs + 200 GB disks
are running for years without seeing corrupted files.  Only time I got a
file been fliped bit is I tried to used OKI 70 ns memory chip on the
100 MHz Pentinum. The point is to convince that dealers, who used memory
in such way, are bad. So, $50 is $50. I'd likt to use it wherever worth
it.
