I got one of those from the first batch arriving in Europe late last year, and absolutely loved it (the closest I ever got to that was an Odissey back in the 90s). But... only a few days after unboxing, the digital part of the synth stopped receiving current from the main board, so to my dismay I had to send it back.
My trust for Behringer's QC has hit rock bottom since, but having said that, the price of that thing is too tempting to ignore. I may get a Gray Meanie when it becomes available again.
Also I got the other one in my pre-modular days, now I can think of a million fun things I'd like to try with both racks interacting.
