Actually I'm taking -- or took -- terrible shots. For forseeable future
plan is to make large negs from some of the hundreds of rolls I shot in
Times Square pre-disney... grab shots, technically, um, run of the roll in
the light du jour -- or de la nuit. But I'm going to take your advice
anyway and get the plus... It's so rare that the expert tells you to do
what you want to do anyway... thank you.

My understanding was that the 4000 is SCSI, the 4000+ firewire/USB.

I'd like to do that, though thought of yet another learning curve is
dizzying... I envision the scanner that comes with a pill. Swallow and
you've got the manual internalized...
meanwhile, thanks again...
& cheers,
