I agree with low_48 about the speed controls. We have one at our turning club, and at a school where I have taken some classes. I find the controls annoying compared to my Jet 1642. The delay in responding always has me pressing the buttons again to try to get it to respond faster. That said, it is a solid machine and I would not turn one down if offered. The other people in the group that own the XP like it, so it is probably more of what you are used to.
I am not sure what lathe you are using now, but the Nova has a 1 1/4" x 8 spindle, so you may need to get adapters/new chucks if you are moving up from a 1" x 8 spindle machine.
