To get the 'classic' Moog filter you definity need a 24dB/Oct 24dB/Oct transistor ladder filter. As @JimHowell1970 said the MiniMoog Model D labeled 'Resonance' as 'Emphasis'. There are quite a few really good filters that would suite. If you search transistor ladder filter one from AJH Synth and Dopfer (both respected brands) will show up, but so will others like something modular (I dont know them personally, they seem to be a relitively new manufacture) and Fully Wired Electronics (but I'll leave my personal bias which is infavour of FWE for now).
It's a shame that is the case with your local physical music stores, its somewhat similar where I am, so I completely undertsand wanting to shop with retailers you know and have dealt with before.
