3 SBR16 sets +3 ballscrews RM1605+3BK/BF12 +3 couplers | eBay

Is it a good price? I want to build a machine around these sizes so it seems ideal.

I already have spindle, steppers and electronics and I plan on building a steel box frame. What else do I need, Is it ok to use steelbox for the gantry too?

I like the look of this machine and plan on using it for reference :)
