I used the ISE filter/hot/cold(not chilled) and it was good. OUr water doesn't taste bad so I don't know how good the filter is, but the hot was very nice. I had an issue after installation (GC was an idiot) and customer service was really good and didn't just keep bank hours.

Have you considered Grohe? Check out these links.

Grohe Blue for cold water

Grohe red for hot water

My GC sent me to a store and the rep. recommended the Bodyglove system (having flashbacks from the 80s).

In my area, we generally have great water. He said that he used to have an RO system and switched to this. He wants minerals in his water and wants just the chemicals removed.

@gemcap: I will check out Grohe. They look great. Thanks

Grohe is stunning! However, it looks they do not offer the Grohe Red in North America and the Grohe Blue is crazy expensive.

Now looking for feedback on:
+Bodyglove
+Aqua-pure
+Multi-Pure

Salesperson has me leaning towards Bodyglove--still awfully expensive to get all three (hot/cold/filter).
