I have read tons of threads on motors for the G540. Seems that Keling has some good prices for steppers for this driver. I would like to know should I wait for the new KL23H2100-35-4B, or buy KL23H284-35-4B now?

These are for my new build which is 4' by 4'. I am using the new 1/2 -8 , 8 Start acme screws. I am finishing up the gantry so I am getting close to the point where I need to work on electronics.

Thanks
Dave
