Charles, The least expensive RO systems I have purchased lately have been on eBay. There are several vendors there selling very inexpensive units. I have purchase two for myself and two for friends to use and I helped them install the units.
If you are only looking for a small quantity of very pure water, why don't you collect condensate from your dehumidifier, or rain water. I started out doing that and found the benefits of it for all my plants that I went to RO water. I can not collect enough rain water some years to keep my plants going. I purchased 5 gallon plastic carboys from a beer/wine making supply house to stored my water in. I could keep almost keep a years supply of water for the 40 plants I watered with it to begin. I got ten of the carboys 25 years ago and I still have four of them. I think they were high density polyethylene 5 gallon carboys. I would not worry about heating the water, just set a container you will water from in the plant area the night before you water and it will be at room temperature for the plants. Or keep a carboy on a shelf that in the plant area so you always have room temperature water to use on the plants. I did that and had a series of tubes going out of it I could water from. The carboy was higher than the plants so simple siphon action moved the water for me.
