[bstronger]

I have found potable anti freeze at Home Depot for
Less than half cost compared to the common
Alternatives.

Usually the cheap stuff at home is blended with alcohol rather than being straight propylene glycol. It's ok for water systems, but not good for engines or other non sealed systems where the alcohol can evaporate. It's also harder on some types of rubber and plastic.
