I fought buying a RO/DI unit for some time once I did I kicked myself for not doing it earlier great investment I got my 100 gpd unit from Melevsreef. for 199.99 shipped it produces water fairly fast probably more than 100gallons in a day. I fill a 32g trash can in about 6-7hours. I still have not purchased a TDS meter yet since my unit is only about 3months old. Also to add to the thread on a related topic

I want to know of a good place to order a decent TDS meter for cheap or if I can just go and buy one locally.

It depends on what you mean by "bottled water."

If you mean distilled water from a store, then that's probably just as good as RO/DI - but you don't really know. It all depends on the machine/facility that is making the water, which you have absolutely no control over.

If you mean bottled water for drinking, then no... I wouldn't recommend it. Granted, it does have the chlorine removed, but to make it taste good, they normally add various minerals and salts back into it. It's probably consistant between brands (same recipe all the time), but not "pure."

Kurt is right, they put stuff in the drinking bottled water to give it taste (what ever that means, I used to drink out of garden hoses and am still alive today), try different brands of water. Deer Park tasted nasty for "pure water" when I tried it years ago.
RO/DI is the best way to go IMO.
Age is relative, you are only as old as you act....of course, this works in reverse....

Questions loved, heeded advice greatly appreciated!

Marinedepot has a few different TDS meters on their site. I think Melev has an inline TDS meter that he sells that gives you before and after readings. I can't remember.
