May have the option to pick one of these up. It's being described as being in perfect condition. Fully set up, around how much should I expect to spend. Are these still considered to be a good setup by Mathews?

I've heard a few guys that have had them and then sold them regret it. They all said they were great shooting bows.
Now Shaw may have a completely different opinion on them as I'm sure he's restrung and tuned a few in the past.
I'm interested in seeing what he has to say since I've been on the fence about buying one to add to my small collection.

$500-600 depending on condition and accessories. Give or take. There is a subtle change from the 2010-2011 model. The 2010 model will have a Z7 cam and the 2011 and newer will have a ZX cam. Not much noticeable difference to me. The ZX cam is interchangeable with the Z7 Magnum and ZXT bows, Z7 cam is not. But Shaw is the expert. We await his input.

I loved my Z7, shouldn't have sold it, but I wanted to try the elite. Now I'm back shooting the heli-m.

Great bow. How much all depends the quality of the accessories.

They are draw specific cams. So if it's the not already your draw length you would need another cam.

Does anybody have any opinions on z7 being any better or worse than the Creed?

I own both. They're about the same to me. I like the Creed a little better because of the draw stop on the cam.

Is the chill a better option than both?

Totally different cam systems. All three are nice. If possible I would shoot them and see which I liked the best.

This ^^^

I don't have a ton of experience shooting lots of different bows but I we the Z7 and it shoots very good. I'm comfortable hunting with it.

I shoot a Z7 and love it. I thought about getting a halon this year but decided to stick with my Z7.
