I'd just watch on ebay, I just got an Adaptec 39320D-R off of it for about 225, which I thought was fairly good-- especially since you don't see them on there often. It's a 64bit 133Mhz pci-x card though. Works fine for me, and if I ever decide that I want to set the drives up in a raid I can- more than I needed, but it wasn't too much more than I paid for my 160 card a while ago.
