electrical help needed: kinda ot

there is a lot of electrical/electronic knowledge on this list
so I thought I would ask here
I have a hardinge hct chucker that is 440v 3 ph
hardinge recommended using a transformer to convert it to
220 instead of rewiring the control box
on 440 it uses no more than 4 amps
where can i get a transformer, hopefully cheap
It mite get converted to cnc but I have to get it running first

thanks
mike
