Roland Promars MRS-2

via this auction
"Rare, unique and programmable (Eight user patches). The Dual VCOs can be detuned up to 1.5 octaves +/-. The two detuning presets can be used to play duophonic parts. The LFO goes into very high frequencies creating weird ring-modulation, FM or bell-like sounds. There is also a sub-oscillator for each VCO and a control input which can be assigned to VCO/VCF/VCA (or all at the same time). Needless to say it has amazing filters (1 HPF and 1 LPF with dedicated envelope) which rival the Jupiter and SH series Rolands in fatness."

"Fantastic synth for the price - two great-sounding analog oscillators, a beautiful, fully-analog curtis low-pass filter, two digital wavetable oscillators, and enough modulation options to make your head spin (4 LFOs, 3 envelope generators, very powerful 16-step sequencer)."
