cbrpage is in extras and quite nice, but I've also updated Comix for Maemo 5 (and updated it for 4.1 as well) to the latest of the 3x branch prior to the rewrite. I'll post it to the Garage site as soon as it's out of maintenance mode and try to get both versions into extras as well, but until then, if anyone would like to try it and know how to install *.deb files (you'll need libjpeg-progs as well):

For N900/fremantle/maemo5:
comix_3.6.5.maemo5v1.0_all.deb
libjpeg-progs_6b-14.osso1.deb

For N8x0/diablo/maemo4.1:
comix_3.6.5.maemo4.1v1.0_all.deb
libjpeg-progs_6b-14.osso1.deb
