I have been playing with a Perq3 QC card
  <http://www.scsi4me.com/?menu=menu_scsi&pid=143>
which isn't anywhere near $15K, and which certainly seems to provide the
characteristic improved performance.

PriceWatch is showing several LSI Logic cards in the $300-$400 range
with battery backed cache, which doesn't seem too out of line.

It would seem a good tradeoff to buy one of these cards and drop a
SCSI drive off the array.
