I have been shooting a Z max for 15 years. It was THE speed bow when it came out. I bought a Mathews EZ7 for this season. I bought one for my 15 YO son first, and really liked it.
I can't bring myself to selling the Z max, but I will probably do so. I really don't need a "back up bow", but I also don't want to sell it for 200 bucks or less. It's worth more to me than that.
Archerytalk classifieds is the best bet for a sale. There are still plenty of folks who shoot z max's
