How about buying distilled water at Wal-Mart?

Gives a rather lean mix with fresh water but can easily be used to enrichen an existing charge if one is placed inline just after the coolant pump....its designed for use with a garden variety watering hose and so you will need to get yourself a male and female "hose bib" if you wanting to adapt one of these onto standard tapered pipe fittings.
Your mileage may vary here--in my case I say "lean mix" because I use soluble oil which is a fairly viscous substance as it comes out of the drum

If you are only talking about a few machines, buy it premixed. A couple of pails of concentrate should take core of topping off for a while.
OK, time for follow up!
Ron Smith, co owner of Star Chem came out to my shop, took water samples, and coolant mix samples. He will get back to me with results, in the meantime, the new stuff arrived on Monday and I have replaced the mix in 1 machine, the VF-5. Cutting 4340 hr right now, part goes into machine at 11 lbs, and comes out at about 13 ounces, good test part, finishes look better already, new stuff is not as sticky, time will tell about rust. FWIW new stuff is Starcut 775AL. Will report findings as they occur.
