That three slot limit is a killer...honestly wish we had gotten 4 slots instead of the personality card slot. I can't have VGA, USB, 10/100 Ethernet, and PCI IDE like I'd prefer.
You can even get localtalk though the Stealth serial port might be harder to findI'd sort of second that, IE, if you want a Rage 128, USB, and 10/100 Ethernet that's all stock in a B&W. What you're giving up in that trade is SCSI and Localtalk ports, although SCSI is easy enough to fix. Unless you simply must have Localtalk it's kind of a no brainer.
