Given you're on the other side of the pond, I would of thought Gecko drives would be a reasonable first choice, as you won't have the issue of import tax and VAT to worry about, which makes them poor value here.
However Leadshine AM/EM drives might be worth considering for the sole benefit of having stall detection, which I'd recommend for any twin screw axis (should a single screw axis stall, it's not normally a major problem machine wise, but on a twin screw axis, you risk twisting the gantry if one screw stalls and the other keeps going - even with stall detection you'll likely still get some twisting, but all motion should stop far quicker minimising or eliminating damage).

Gecko used to also sell some pretty low inductance Nema23 motors, but I see they've stopped selling them.
I'd have a search of the more American based forums to see where people are sourcing motors.
