Depends how much money you want to spend, but for most work a 600 dpi 32 or 36 bit scanner is fine. Make sure it is USB (and don't figure on Win 95 for USB) or SCSI, the printer-port scanners are too slow. A 8 1/2 x 11 RGB scan at 1200 dpi is just under 400 Mb, incidently, so you will not be using that resolution all that often for big scans. I like Microteks, UMAXs are also nice, Apple doesn't sell them any more, HP Scanners have a poor interface, never used a Cannon, but I doubt if they would be less than nice..
