I agree, the 8 bit solutions are obsolete.
Btw you can get a single board that integrates the Arduino Due, the stepper drivers, heater mosfets, SD card socket etc. It's called the Duet electronics. One of the really nice things about it is that it also has an Ethernet port, so the firmware that is normally run on it provides a web interface as well as USB.
