Nice gear, Garth! My compliments.
I got a used HP 3468A Multimeter some years ago. It connects an HP41 via HP-IL so it doesn't need more interfacing than just this.

Finally, I am waiting for my first module to plug into this thing (Stat Pac). That will be an interesting new experience too. Maybe I will start searching for a card reader next? I guess this modularity is what makes it really shine.

Welcome to the world of HP41 modularity!
As original modules are rare but practically all ROMs are more or less easily available, a neat gadget to encase them and make them accessible to your HP41 are Diego Diaz' Clonix and NOV-Ram modules. However, I don't know if he is still active.
A module of its own to consider is the HP-IL (HP 82160A). It grants access to other peripherals, such as the HP 82162A Printer or the HP 82161A Cassette Drive. You may use the HP-IL to connect your HP41 to a computer via serial/USB link if you are interested in more recent uses of the device. Check J-F Garniers site (PIL-Box).
