which ro unit to get?

[canadawest]

I find my tap water is VERY high in phosphates, and of course there is plenty of chlorine as well in our municipal water, especially late in the summer and winter when resevoirs are lower.

I just figured I would save money in the long run, rather than lugging two 5 gallon jugs to Safeway once a week for RO water @ $2.99 a jug.
