I tried Cocolo before and it only lasted about a month and a half before I got bored of it, I would say go with the Puni Ana SPDX, I had the Puni Hole DX before and it lasted a pretty good amount of time (a few months each time I buy one).

Personally, Puni Ana SPDX looks best. Bone frame looks amazing, and design seems enticing. I've been struggling as to whether I should order it or not myself as well, but it'd be hard to store, and it's quite the investment…
