<p>If you should find that you need more than one SCSI controller in a
PCI machine, you may wish to consider conserving your scarce PCI
bus resources by buying the Adaptec 3940 card, which puts two SCSI
controllers (and busses) in a single slot.

recommendations except to say "SCSI over IDE whenever you can afford it."

Wait for Triton-II.
Use Triton-II based motherboards if you have the choice.
