Axion makes nice stabilizers as does Doinker. Try a few different ones out and see what feels the best for your setup. If you shoot 3D you may want a different stabilizer than your hunting one?
NAP is expecting to have stock on the Apache stabilizers sometime in May or June. They're still in production right now. As soon as they become available I'll have one on my Z7 Xtreme.
I just added a stab on my bow Saturday. I shot 7 or 8 different ones and chose one from EAP called something or other. It is a 7" with carbon rods with weight disks out front. This helps me reduce the float more than anything and that is what I was looking for. I paid $60 for mine would have been better if it was $20 but it is what it is.
Limbsaver S-Coil does it for me , can't see the point in spending stupid money on BowBling , I'd rather save the money for another game Tag .
The one I bought looks very much like the one on your Z7. That Z7 is a sweet looking and shooting bow.
