9114B disc drive vs 82161A tape drive
I'm thinking about trying to find one of the above in working condition for my collection of 41s. I already have an upgraded HP-IL module with an Extended I/O module. I intend to use the disk/tape drive as backup storage of programs and maybe for future data storage. I have a working card reader and an untested parts/backup card reader and a good supply of magnetic cards.

9114B
Pros:
Battery is easily replaceable with a new 6v gel cell of equivalent size.
Uses 3.5" floppies (I still have a bunch of these and they seem to not be degrading)
Reportably "robust" and reliable for an old device with a high probability that it will work
Cons:
Harder to find
Has some compatibly issues (wakeup and sleep issues) with the HP-41 since it was not originally designed to work with the 41.

82161A
Pros:
Battery rebuild is a little harder, but do-able
Designed to work with the 41
Easier to find
Cons:
Tapes are very hard to find and will probably need new felt pads to get them running when sourced.

Are my pros and cons hitting the mark? What have I missed?
