Questions About NEJE Max 4

My old Diode laser that started life as a NEJE Master 2S but got upgraded until the only thing NEJE was the control board finally crashed. I have only been using it for chopsticks and similar for the past year because it is very slow. I have CO2 but find the occasional times when a diode is better.
I’ve been looking at the NEJE Max 4 E80 with all the bells and whistles, mostly because of the Z axis control that would be handy for some of my projects.
For the people who have one; how do you like it and is it worth the money?
Cost wise here in Canada, it is more than most K40s but I already have two CO2 units and wouldn’t mind having a Diode again.
