The Taig or 150-Lb mini-mill seem like they would work. Most likely
the CNC Taig with its higher-speed spindle would be a good choice.
The Y travel is about 4", so that should be enough. I retrofitted a couple
of Taigs, and was pretty impressed with them.

I have not really tested out the Taig spindle to see how accurately it
runs, etc. But, it all seems pretty well made.
