Thanks Irving, bearing in mind I plan to do a cheap and cheerful MDF build first and then improve on it, would these cause me any problems?

Makita RT0700C 700W Router - For £90 it seems to be a steal and more suited to cnc use then the Bosch Colt which gets used a lot.

And these 4nm Nema23 steppers - seem like overkill but I can reuse them in a bigger machine later on.
