As you said, they are cheap. Buy two and rotate.

I'd think it's reliable enough if you have some redundancy. Maybe
Mon-Wed-Fri on one, Tue-Thu-Sat on the other?

A slow uplink might be OK if you're only transferring diffs over the
network (see software recommendations) and doing it only during off-peak
hours (at night). Maybe not too expensive if someone trusted can either
host at home or at a partner organization.

Some things to check out:

These might be applicable to either offsite or rotated removable hard
drives. Whatever you do, test your backups. Only thing worse than no
backups are backups you _think_ work, but really don't.
