I use the Wal-Mart filtered water that they sell in bulk, big blue machines (collagan or something like that). Believe they use a RO process. I buy the 5 gal jugs for about $6, refills are 40 cents a gallon, I've got 5 or 6 of the jugs, had them for a few years. Becomes cost effective rather quickly if you use a lot of distilled.
Here in Missouri we have very hard water, lots of lime, can really ruin a rust blue or CCH job.
