I guess I could get the unmixed antifreeze and mix my own with "purified" water from a super market. Probably less expensive than the premixed. A 25% mixture would provide enough freeze protection while maintaining the other advantages of modern antifreeze.

John, why not? Seems a good plan to me, just check and make sure a 25% is adequate for your lowest expected temperature. Using distilled, RO or deionized water may be a case of over-precaution, it's just so damn cheap I can't see why not to do it.
