Not sure whats available today, but if you don’t mind used or NOS… the 4Sevens quark AA-T is an exact match to that programmable user interface. I use the 1AA version for several years, very reliable… although not the brightest by todays standards at ~220L on a 14500 IMR. IIRC there was a 2AA version as well.
If you’re looking at Gene malkoff and Elzetta, the 47 lights will be less of a $ticker $hock as far as pricing goes.
