Mayba something like this?
Sry the original links were so damn long.
To me these seem like the same product but i linked them both, also any vesa arms you can find will fit the back of the cintiq 16. something like this, but be sure to check how much weight it holds, this solution might end up becoming more expensive than the wacom stand.
I am not happy with that stand lol. I bought this and I love it.
