JX-3P even without PG. Kills the Akai.
BTW in the UK 3Ps on their own in good condition can go around £200-£250 - sometimes cheap as £150 if needing work or scruffy. The PG-200s go from around £200 - £250 (as much and often more than the synth) so overall £400-£500 - in dollars that's over $700 so the seller is about right. The AX73 is dirt cheap for a reason. Not that good.
