I have a Black Widow 9636 Pro scanner, running under Windows 95, which I have used to scan a half inch thick earing, in 3D. The results were very good.
The SCSI II card is very basic and supports only the scanner. Daisy chaining in not permitted.
It cost me about £300 back in 1998. $12.75 sounds like an absolute bargine, but remember as Pesala points out, it's not suitable for Windows 2000 or XP.
