It all comes down to the cash factor doesn't it.
A combination would be nice indeed. Bellow is my wish list - which probably won't happen in the near future.
Analogue
Desk with sweet EQs.
Compressors.
Pre-amps.
Bass synths.
Digital
Sequencer.
Distortions, delays and most other FX too.
Multi track recorder.
Synth sounds that need heavy modulations and leads.
Sampler.
