Favourites I own -
Roland System 1 - I'll defend to the hilt, the SH-101 plug out is spot on and the System 1 synth is very worthy.
Yamaha CS01 - PWM like no other, a beast in a Casio case
Elektron Analog Four - Has that warm Roland sound, plus Overbridge DAW integration.
Favourites I sold

-
Roland JX3P - Gorgeous pads and now going up in price.
Roland JX10 - The lushest, warmest 80s pads I ever heard but a total dog to program
Yamaha AN1X - Sorely underrated, equal or better than the JP8000, please make a module (not the AN200)
Roland JD800 - The look, the sound but sadly the size too.
Worst: Roland JV1080 - so uninspiring, a real bland pop toolbox.
