Korg MS2000, or maybe something else for $ 400?

hello,
First, I wanted to buy a midi keyboard, but I decided that I will buy synth to $ 400:) My choice is a Korg MS2000. Recommend me some other synths for that price. I making electronic music (Ableton): experimental, ambient, witch house, minimal synth, minimal wave, synth.

Thanks for any suggestion!
