I finaly found a Solton Programmer-24 for a semi-realistic price. Defective, though (sold as defective - not a scammer).
Wish me luck my local tech can bring it to life again...

Oh, and I bought an Akai Timbre Wolf (modded, without keyboard, angled desktop now) for cheap (hasn't arrived yet).
I'm totally into super-minimal sound engines; they often make perfect FX fodder (I learnt that with Fugue Machine's inbuilt sound engine).

Cheers,
Bert
