In the past I've had a rack of Roland modules, Oberheims, Prophets etc etc. All the old analogue kit is expensive nowadays and rarely to be seen here. Most of the current offerings being primarily digital I'd just grab an Arturia Vintage collection and decent mother keyboard. Arturia in fact offer a couple of keyboards with an accompanying software package containing sounds selected from the collection ( editable ) at pretty decent prices.
At seeing the mention Of Oberheim above makes me smile. My son in his Doors mode with a Jansen 1967 transistor organ and a little short keyboard controller plugged into a Oberheim piano module doing bass note duty. Was quite Manzerek.

I’m a real fan of the Roland ROMplers, just sold my JV-1080 to move to an XP-80 (workstation keyboard with a JV-1080 in it). The expansion boards are getting pricey now but luckily I already have the two most collectable ones from back when they were about $50.
Also making a start on building my own modular synth setup for some analog goodness on the cheap (if you don’t value time).
I have a Novation Circuit for jamming out on the couch.
My current list of Synthamasizers : Moog Sub Phatty Roland SH-101 Roland MKS-50 Novation K-Station Korg 03R/W Korg Wavestation SR Korg Poly800 Korg MS-20 mini Korg MS-10 Korg Volca FM Paia Fatman SOMA Lyra 8 AtomoSynth Mochika XL Synthstrom Deluge Arturia MicroBrute
And about 750 HP of Eurorack modular stuff, which is pretty fun.
Softsynth wise, I quite enjoy the Arturia Collection and love Diva and Korg Legacy stuff. For me, the physical stuff is mostly about how it inspires particular things and the hands-on nature rather than the sound itself.
AvonSynth look like they just popped up, saw them advertising on the NZmodular facebook page recently. Seems decent, if a bit uninspiring (basic range of modules/functionality to start with). Keen on more local stuff though, so will probably grab a module or two.
