The issue I see with the DX200 is the lack of a proper computer editor. And if I remember well, it didn't work well with win XP.
Also with the DX200, you cannot edit all the FM synth parameters with the user interface, you need the software to do it.
As for the sounds and mangling, it had a good presets selection as they were pretty much over the edge preset in the 90es, so not hear alot.
I sold mine, but do regret it a little bit in the end.
