Stumbled across this: CrashPlan bigsale
Right now it's 94% off their normal 1yr backup plans. With GST, it cost me just over $11 for a family plan. 2-10 computers, unlimited data. The discount goes down every two hours.
If you're looking for an offsite backup solution, definitely have a look.

Move to the next mob who are having crazy sales. :)
Yeah, I'll have to reconsider in a year... but at least for the next year I've got offsite backups for a damn good price.
