I want to buy a simple and warm sounding analogue VST to complement my current setup:
Gforce Oddity 2
Synapse Audio Dune
+ Logic internal synths
I make electronica. And i really love the filters and warmth of Minimonsta. I want something that covers all sound areas and is simple to tweak and use.
Currently looking at Synapse Audio The Legend
Really depends on what type of music you're making. But well, you already have a minimoog emulation, so I'm going to recommend you a few different choices than others have given.
Arturia Moog Modular - This is about as warm and analog as it gets. You can make it as simple or as complex as you want, as it's a full modular emulation. If you can spare the money, then get all the Arturia emulations with the Arturia V Collection 5.
Imaginado DRC - Very unique and often overlooked synth, that has some very nice analog warmth.
SynthMaster One or Synthmaster 2.8 - Very nice sounding synths, and the latter can do just about anything you want to throw at it.
u-he ACE - basically a little gem of a synth, which can produce a whole range of old analog type sounds.
GForce ImpOSCar 2 - You already have GForce synths, so why not add this one, as it's another fantastic little gem.
