Here's my progression from the age of eight (not necessarily progress:-) - that's a different thing).

Acoustic piano,
Hohner Pianet N,
Watkins Telstar organ (about the same size as a current 61), way cooler than a Vox Continental or Farfisa Compact Duo,
Hammond L-102,
Hammond M-102+Micromoog,
Roland E38,
Korg i30,
Korg Pa1XPro.
