Thanks for all the replies!

I decided on an Epson Perfection 2480 Photo (still some
remaining pieces sold, and sane homepage claimed support).

And, it works :)

After I fixed file permissions on /dev/ugen* and /dev/usb* so that
the scan user can rw them, scanimage -L reports:
device `snapscan:libusb:/dev/usb4:/dev/ugen0' is a EPSON EPSON Scanner1 flatbed scanner
and I don't need any uscanner devices.

Perhaps run 'scanimage -L' or 'sane-find-scanner' as root once,
without uscanner in the kernel, to find out if it works?
