That's a pretty *large* machine you have in mind. Why do you need the 3' z axis?
The problem is that the frame for such a wide and high working envelope must be very rigid. This means expensive.
If you could manage a z axis height of 12" or so then you stand a good chance of achieving your objective of keeping the price to a reasonable amount.
