Vortex Sound Research

I just graduated from music school and audio engineering and started a basic salary job. I have messed around a lot with virtual synthesizers, from programming them to modular emulators and tons of virtual instruments. I'm looking for one with a wide variety of possibilities by itself, it doesn't have to be a basic one, maybe even a more complex synth. The thing is the dollar conversion rate to my country's currency is very high, so I'm in a budget, it would be like i would have to pay 4x the original price with a basic income. Taking all of this into account, what would you recommend?
