I have four Wantai DQ860MA stepper drivers and four KL34H280-55-4A stepper motors that I plan on using in my router build. The specs for each are below:

DQ860MA Drivers:

Input Voltage: 24-80 VDC
Input Current: >6A
Output Current: 2.8A - 7.8A
Consumption: 80W

KL34H280-55-4A Steppers:

NEMA 34
Current: 5.5A/Phase (Bipolar Parallel)
Inductance: 4.0 mH
Resistance: 0.43 ohms

Can someone please recommend a power supply to power these four steppers? I haven't found a good source for anything in the 70V, 1kW range. Thanks in advance for your help.

Hack an old arc welder into a ferro resonant power supply, beefy and cheap, but wastes a bit of power from iron losses.

How about something like this:

Antek - PS-10N70

(however lately they seem to be out of stock)

Thanks for the recommendations. I ordered a KL-6020 from Automation Technology (60V, 20A) late last month simply because it was in stock and I was pressed for time. I am in the process of finishing the wiring this weekend.
