My cumulative savings are now at $674. Balance remaining on the DVR setup is $2057.
My average monthly savings for the past 6 months is $112 - if that remains the same then the DVR setup will be paid off in about 18 months. I suspect it'll take a little longer than that though as some of the "delayed release" series like Game of Thrones tend to cost a bit more than the content I've bought so far. The Drobo's also been slowly filling up (it's now 64% full), so I foresee an additional drive in the near future. Adding the 4th drive will double the Drobo's data capacity (don't forget I'm using Dual Disk Redundancy).
