Advice on converting my VMC

[Proteus]

Ok, so far i have to deside on the following options(all being Nema34 With original gearing ration and belted):
X/Y axis Option 1: KL34H260-42-8A Stepper Motor – 465 oz in 6A With KL-8070D Digital Bipolar Stepper Motor Driver-32 bit DSP from Automation Technologies
X/Y axis Option 2: KL34H260-35-4A Stepper Motor - 465 oz/in 3.5A With KL-8056D Digital Bipolar Stepper Motor Driver-32 bit DSP from Automation Technologies
X/Y axis Option 3: 34HS7840 Stepper Motor - 567oz/in 4A With DM860A Stepper motor driver 7.8A 256micsteps 24~80VDC from longsmotor666 (eBay)

Z axis option 1 : KL34H295-43-8A Stepper Motor – 906 oz in 6.1A With KL-8070D Digital Bipolar Stepper Motor Driver-32 bit DSP from Automation Technologies
Z axis option 2 : KL34H260-42-8A Stepper Motor – 465 oz in 6A With With KL-8070D Digital Bipolar Stepper Motor Driver-32 bit DSP from Automation Technologies
Z axis option 3 : 34HS9805-37B2CNC Stepper Motor 880oz-in 2A 8wires With DM860A Stepper motor driver 7.8A 256micsteps 24~80VDC from longsmotor666 (eBay)

A/B 4&5 axis cradle : Belt driven og geared Down Nema 23 465-650 oz/in with KL-8056 or DM860A Drivers that will be decided later.

Controller Option 1 : CSMIO/IP-S 6 axis Ethernet Motion Controller (STEP/DIR)
Controller Option 2 : C11 – R9.6S751-9 6 axis, Multifunction CNC BoB with Relay and Spindle Control
Controller Option 3 : Suggestions ?

Considering the old Nema34 steppers delivered (a stunning ) 212,4oz/in, the new steppers will deliver twice as much for X/Y and even mor for the Z axis.
The new drivers will all be compatible with new controllers and Mach3 or 4, deliver a bit more cirrent, AND will have microstep option.

I have 3 questions i was hoping i could get some quick reply on before i purchase these parts.
1. Will C11 handle 6 (in reality 5) axis at the same time when 3D milling parts on my 4&5th axis cradle considering the BoB itself, and the fact that it utilizes the parallel port?
I mean, the CSMIO/IP-S is NOT cheap(for a good reason) at nearly 5X higher price compared to C11.
However i do want to utilize my ATC in time(which the C11 can`t handle without a PLC). Both will handle my existing DC milling motor and driver

-*-

2. Any good reason why i shouldn`t by from longsmotor on eBay instead of Automation Technologies Inc ?
My brief experience with Automation Technologies is very positive, but my impression is that longsmotor seemingly delivers good quality and service. AND somewhat lower price.

3. Should i keep my existing 220VAC/60-18-12VAC tranformer or og for a solution with tripple 24V/8.3A Switching CNC Power Supply, or dual 48VDC/12.5A Switching CNC Power Supply.
Have no idea about the Power output from the existing Torodial PS, but if they did the job when constructing the VMC, it should be able to handle the drivers at max 5 Amps.
That should be 60Vac x 5Amp x 3 drivers = 900W +10% = Approx 1000W. Could try loading it to find max current at axeptable voltage drop, but thta would mean a powerful regulator should be used.
Keeping it at 24V with New PSU means lower noise and should perhaps be considered.

Appreciate swift advice and suggestions gentlemen.

(By the way, old bearly used and functioning electronics and motors will be sold if anybody should be interested).
