From my experience of learning mt on the Z.... In the long run it is worth it and you will love the manual on this car. That said, the learning curve is horrible. I and many of my friends agree that this is one of the hardest cars to learn stick on, the low end torque isn't there on these cars so you really have to get a feel for the clutch.
This is my personal experience though, so take that for what its worth.
