I can't dispute your utility assessment (for your location); and whether
instrument flying is fun is a subjective matter (though I agree with Jose
about the visual beauty of flying among clouds). As for time to learn
(especially if you previously got right up to the signoff) and maintaining
proficiency, I think both can be done conveniently and inexpensively by
using MSFS. (That doesn't count for official currency, of course--but
currency can be maintained with just three approaches on each of four days
per year.)

Gary, I would not fly in the soup with someone that only dose the min in
requirements each year at the controls! yea they are current but they are
not proficient.
