If you like Depeche Mode and want to do that style I'd suggest a synth/workstation. The arranger is going to give you great acoustic sounds, but I think will fall short in the synth department for sounds. You may want to consider the following.

Roland: Fantom (even the earliest fantom is good) Maybe a used XP-60 or XP-80

Korg: All Triton models will work well. You may even consider the earlier Trinity (great synth)

Yamaha: Any board from the Motif series. Possibly the older Yamaha EX-5 or EX-7

Newer synths have styles, but not in the way of an arranger. The Motif is a good example. It has preset drum patterns that you can use and edit. Plus models that have samplers will be beneficial too.

All these models vary by difficultness in the OS. Personally I think Roland synths have a good OS. Korg is fairly easy as well. The Tritons (except the LE) have touch screens to simplify navigation. In my opinion the most difficult one may be the Yamaha Motif. Once you get the hang of Yamaha's OS it's quite easy to operate.
