the rest of these synths I don't know much about.
Yamaha: (2x) DX21/TX81Z, FB-01
4-op (4 oscillator) FM - the DX21 is a keyboard, the TX is a rack, and the FB-01 a half-rack. I was keeping an eye out for an FB-01, as it's the cheapest entry into hardware FM, until I lucked into a TX-7 (rackmount DX-7, 6-op). The FB is only editable over MIDI, and I think the 81Z has more oscillator waveforms available or something.
If I like M I might well buy the current version
Hah, I'd forgotten that had been ported to OSX. Now that would be amusing - running the same sequencer on your new Macbook and a Plus
ZOMG 8-o Casio FTW!!
