Also, what kind of difference would I see in the water between the various models. I'm looking at the 4 stage, and we have pretty good water here in Vancouver. 
 
What is a 4 stage going to give me? Compared to say the water store where we go to get jugs (they have huge tanks and appear to be a large scale RO/DI type of thing). 
 
Thanks.

the difference between the 4 stage and 5 stage is the extra carbon filter that has catalytic carbon in it for filtering the chloramines in your water supply.
the 4 stage ro/di will give you 100% pure water 0 tds
