Hi jascure
I drink ozonated reverse osmosis water when I drink water, which is many times a day. I refrain from drinking ozonated water just before and for an hour or so after meals. I don't much believe in soft drinks, glucose-laden fruit juices and the like, so water is what I mostly drink. I like herbal teas as well. I ozonate a couple of gallons of water in the morning with a medical machine and just drink it all day.
As for enaly machines, I did not have much luck with the model 300 though others were happy with it, but others on the forum have recommended the model 400. I personally have not used the model 400 so i will not comment. Keep searching the auctions on E-bay for Enaly. Sometimes they go very inexpensively. Just keep trying until you get one for the price you want to pay. Be careful about the shipping costs. They tend to be rather expensive, so take this into consideration.
Just for the record, you can get most of the benefits of ozonated water with food grade H2O2. It's just a slightly different source of nascent oxygen. You could drink a lot H2O2 (Hydrogen-Peroxid) a few drops at a time with water for the price of an ozonator if money is really that tight right now.
hope this helps
Cheers,
Paul

I wouldn't drink H2O2 (Hydrogen-Peroxid) with more than a drop or two. I believe it can damage your stomach's ability to produce HCL, creating greater health problems. I purchased a hot tub ozonator (MCD-250) for $250 from a place in California. The girl is very helpful. This unit uses a new, very simple technology that makes all other units obsolete and they put out the same amount of ozone as a professional unit for much cheaper price. You just need to open the unit and modify the connectors. To get medical oxygen, just find a home medical delivery company and find where they gas up in the morning. Wait there for a driver and approach him with $$. Most drivers will gladly accept. I offered my driver $50 and $20 refills. Only refilled once after a,most a year. E tanks last a long time on the lowest regulator setting which you can get on ebay or amazon. For $50, I heat welded an ozone suit from (ozone safe) body bags and just stand in the bathroom steam sauna for half hour (no access to a dry sauna). I put a bowl of water w/potassium Iodide below the steam outlet to (hopefully) mitigate some of the chlorine from the steam.
