In recent years,I've been fortunate enough to have come across a brilliant German software developer named Andre Laska(TubeOhm)...who makes some very high end,but very affordable soft-synths(and he even has freeware available to download.)
His synths are very distinctive and unique,as he offers a trademark spin on various forms of synthesis,including FM,Phase Distortion,Granular,Wavetable..etc.,.
He also specializes in 80's type sounds and even has patches that model the sounds from famous artists like Jean Michel Jarre.I've been collecting his vast array of synths(all of which,are well under $100.
My latest purchase,is his Super Bruno 3 synth and I wrote a song and made a video,to exhibit this man's sonic wizardry and all of the tracks(apart from the drums and bass,are exclusively from this one synth.
