The you also need a KT8A to use the MSC8-DJ 128K memory card (or, IIRC
4 x 32K MSC8-AB boards). They are somewhat rare.
For the widest audience, I'd recommend a v3-compatible 12-bit
Z-Machine for 32K, and then, perhaps, tackle the v5 problem, perhaps
on a 128K -8/a.
For the record, I do have a KT8A and a 128K board (and the -8/a ;-),
but back when I was using them all on a daily basis, the best use I
had for the extra memory was a RAM disk. There just wasn't that much
software written to take advantage of the extra memory, so conversely,
not much was sold because it was difficult to find something to use
it. Couple that with the fact that the 128K expansion came late in
the PDP-8/a lifecycle, and it's not difficult to see why they aren't
common.
I've never seen those particular add-in boards in a machine in the
wild. I bought mine from DEC resellers.
