.. Since I had a 909 in the past and I currently have a DrumStation in my rack, I can definitely confirm Ruud's story.
If you need a simple drum synth, the DrumStation might be a useful addition together with other devices - but if you really
want the sound of the 909 BD (and the other bunch of sounds), well... only the 909 can provide it.
Plus, the feeling of pushing those computer-like buttons with integrated led is an extreme luscious pleasure
Anyway, since I am not any longer into the sound of the 909, I am fine with my stuff.
I love my 808, I am not going to sell it for any reason, even if I should go completely broke and under a bridge I still
would have it by my side.
It's scratched, pots are noisy, sometimes the fills do not kick in when requested... but it's my 808.
It has been in the most strange places in Italy and survived with just the minor scratches
Still on Roland TR's, there is someone here in Switzerland selling a Devilfish 606... for 2000 CHF if I am not wrong.
Anyone interested, I can point you to the ad. It's not on Ebay.
