Canon Pixma mx892. It is listed as "Testers needed!" on "http://www.sane-project.org/sane-mfgs.html#Z-CANON"; for the MX890 series.
I got one, it's been tested. Using "PIXMA_EXPERIMENT=1" on SANE-Backends-1.0.23 it successfully scans at 300 dpi and 600 dpi. Higher resolution segfaults and I would like to know where is the most appropriate place to post them, if they could be helpful. Either way, I was surprised to find that it is usable already. Let me if I could be helpful.
