The names you see on these forums are all high quality, and any would be a good purchase.
All the RODI units work on the same principle, and units with the same Gallon Per Day rating often use interchangeable parts.
ANY home RODI will be an improvement over schlepping to the LFS for water.
There are a number of good units that will fit your needs. Compare them based on GPD, rejection ratio, and 'other features' like TDS meter, flush valve, 4-stage vs 5-stage.
