Although I don't need another scanner, I'd like to add that I have used a HP ScanJet 5c, which is only the next model after the one being offered here, and it was an excellent full colour scanner with perfect Amiga compatibility. The software is available and very easy to use, with all the options you'd expect, like fast black & white preview, then you can select an area you'd like to scan in full colour, or select the whole page. I ran it with an Amiga 1200 with 8MB Fast RAM and a Squirrel SCSI interface in the PCMCIA slot (so the RAM was reduced to 5.5MB) and it worked fine.
I'd recommend a SCSI HP ScanJet to any Amiga user in need of a good, solid scanner. The only drawback may be that they're quite a bit larger than today's slimline models, but they're built to last!
