For the past year I've been using this bassoon stand with my Zendrum. Prior to this I was using a modified guitar stand like the kind most Zendrummers wind up using, however I found out first hand how unstable those can be.
I experimented with violin, saxophone and mandolin stands among others in a search for a better, safer Zendrum stand. Eventually this led me to the Hercules stand.
While a little bit pricier and somewhat heavier than a guitar stand I feel this is the perfect solution for the Zendrum ZX (and probably the EXP model). The stand is rock solid and it fits the Zendrum like a glove. It cannot easily tip over and the Zendrum stays puts even when bumped around. If you're looking for a solid Zendrum stand then I highly encourage you to check it out.
Here are some pictures of the stand folded up and in action.
