Mathews Z7 Extreme Cam Question

[soupcreek]

My 15 year old grew out of his youth bow. I picked up a used Mathews Z7 Extreme for him from my cousin, but he will need a bigger cam. My son is only 15, but he is 6'4" tall and will have a 30-31" draw. The bow currently has a 28" cam. Where is the best place to find a good replacement cam? Are used cams OK or do I need to go to a dealer to get a new cam from Mathews? Any help is appreciated!
Thanks,
Soup
