I am looking to add a VMC to my shop don't plan to use it for day in day out production mainly more of a hobby than anything (I like making curls and chips) but will be doing small runs of say 100 parts or so at a time from time to time I would like to have a 4th axis ability.
I like the idea of the conversational programming I am not a machinist and don't know G code but have been studying to learn it I also have a 22 yr old son graduating college that wants to learn it so I may let him run it.He has a little experience with the cnc world.
Here is a list of machines I am considering and would like opinions on them from y'all;

Hurco BMC 4020 Ultimax control mid to late 90's year model

1995 Haas VF3

Mori Seiki 35/40 Yasnac control ( I think )

Okuma MC-4VAE20 1991 ( not sure about controls )

I think all theses machines are comparable in size and performance ?

Thanks
