Where to buy inexpensive, reliable stepper drivers in Canada.

I am in Canada.

I have a 3-axis CNC machine from around 30 years ago that I am refurbishing.

The original stepper drivers are all broken and horrendously inefficient.

I have purchased one "DM556" driver off Ebay that works with every axis.

I am totally certain that alll other components (stepper motors, parallel port card, power supply, breakout board, and mechanical parts) work without problem.

Power supply options are: ~40VDC and ~40VAC

The motors are 4.6A steppers.

I need a driver capable of 4.6A (at least)

Where should I buy 2 more drivers for the other two axes?

I am not buying from Ebay ever again.

I am not dealing with USPS shipping either.

Might be worth having a look at. I used them in the past, no issues with the drivers I've purchased. Being in Australia shipping is always through the roof, but hopefully that wont be the case for Canada.

Nice place but spent too much time partying when I visited for a month or so in the early 90's.

Automationdirect (dot com) ships to Canada. Excellent selection of drives, etc. and other supplies.

Moons Industries also holds stocks in the USA. They are a quality industrial unit so may not be so economical

Which of these is the best?

The motors are all 4.6A steppers

These drivers are only 4A RMS. Do I need 4.6A RMS?

I think 6.5A peak is correct.

4.6 times the sqare root of 2 is a tiny bit over 6.5.

This one looks good too:
