RS7000 vs QY700

[cuinjune]

Hi I'm looking for a nice hardware sequencer.
I make IDM/glitch type music.
I have an Elektron Machinedrum but it is not good for sequencing external synths, so I'm trying to buy a nice hardware sequencer.
the person I know is selling QY700 for $200 at the moment.
anyone ever used QY700? should I buy this QY700 or look for more advanced sequencer like RS7000?
