With VB3, UVI Retro Organ Suite (I'm surprised this one doesn't get more love in the forums. UVI updated/expanded their Organ Suite to this late 2015 and I thought they did a great job), and Melda's Vintage Rotary, I'm pretty much set on the organ front.
At least, that's what I'm telling myself to combat the GAS and stop buying every new plugin just because it's the latest and greatest B3 organ/multitap-delay/didgeridoo since, well, the last B3 organ/multitap-delay/didgeridoo that suckered me in.
