We can't get anything 'great' in the u.k. imo (it sucks).
Looking like these are what I'll be going with:

They're 4nm with 3mh inductance so I'll be using them on 60v supply for x,y.

I'd like closed loop but not as a 'kit' which is out of budget.
Something like a 4.5nm motor around 2mh ind, 80vAC driver and a 2x 35vAC toroidal wired series for 70v.
Ah well, maybe later on
