haha, scsi card may be more expensive than your scanner.
If you buy a 2940, used one is cheap as 20~30$. But it is not
good one, very slow. But 2940UW will be 60$~80$, depends
on case (normally depends on the 68 pin cable.) But it is
still slow.
Seems you are not that professional, 2940 is enough for just
scaner.
