You don't need any special SCSI cards. I got an Adaptec AIC0-7850 PCI SCSI card for my PC, and it works fine. It's an older model, and it was super cheap on ebay (10 bucks including cables). I found the drivers on
www.driverguide.com and was good to go in minutes.
Point is, don't worry brand-wise, just make sure it's a SCSI card and not just parallel. I use mine with various equpiment, Zip, SCSI Hard Drive, and External CD-Rom. Good luck with your SCSI, it's made my life a whole lot easier.
