My long-serving Epson Perfection 1650 has died on me so I need a

It looks like it's supported by GPL code in the genesys GL847 backend in
the stable release of SANE. So, it should work well, most probably.
The only other possibility seems to be a combined printer and scanner,Beware, combined scanner/printers are usually not well supported by
but I don't need the printer and want something that doesn't take up
too much room. Any advice please?
Linux. e.g. HP LaserJet 100 color MFP M175nw scanner doesn't work
properly even though HP claim to support Linux. If you don't need the
printer or copy function, why would you buy that anyway?
HP OfficeJets work perfectly as do the lower end HP All in Ones. I'm using
an OfficeJet with Fedora. For a stand alone scanner the Epson perfections
work, however you have you to download a driver. My girlfriend just got
the EPSON Perfection V30, it's running on a Fedora 14 system. I downloaded
the RPM and it works fine.
I don't know for OfficeJets, but, I download HP LaserJet 100 color MFP
drivers, and it has severe problems with the scanner.
1) Scanning on the flatbed with the hp-scan tool is slow as hell,
eating loads of CPU (probably because it's a python script). That's
unfortunate because I wanted to connect it to my server which is an old
K6-2 550 Mhz computer.
2) The SANE backend is fast, but don't support the ADF (Automatic
Document Feeder) at all. The hp-scan tool "supports" ADF, but outputs a
PDF file containing buggy pixels... It looks like the image is
stretched in a parallelogram and cut in several planes of pixels.
3) The SANE backend must be somehow buggy, as scanimage(1) works, but I
couldn't get any GUI frontend to work (xsane, xscanimage). Although
they can find the scanner, they fail to scan. Strangely, sometimes I
could get them to grab sheets in the ADF, but, they still couldn't
produce any image. Moreover, scanimage(1) through a network (with
saned), fail after a few seconds with an error "sane_read: Operation was
cancelled".
4) Scanning fail sometimes with scanimage(1), and fails always with GUI
frontends, but, unfortunately, when it fails, any further scanning,
fails with a message "Error during device I/O" until it's
unplugged/replugged from the USB port.
5) A closed-source binary blob is required for scanner drivers.
GENERAL ISSUES (due to crap firmware, not really drivers):
6) It's not possible to get any image that's not affected by JPEG
artefacts even when asking uncompressed raw monochrome data.
7) Although the printer works on Ethernet, the scanner function can
only work through a USB connection.
These two issues exist on Windows too. :)
The printer, as PCL or PostScript, works quite well.
