I bought my Aquasafe unit (6-stage 75 GPD) and love it. I tried the safeway method for a while, but you go through so much water, I found it WAY more practical to buy a unit. Mine was $165 with a Milwaukee TDS meter and tax & shipping - Direct from aquasafe canada.
Beware of TDS readings as they are not a good indicator of toxicity of water. They only measure the amount of charged ions in the water to be used as a rough guideline. One of two samples of water with the same TDS reading might be toxic while the other is pure.
