Hey Doch,
I just purchased this system for my home.

I also purchased this add-on piece so I don't waste as much water.

the pressure guage is also a good idea. it will give you an indication as to when you need to replace your filters.

The best thing about buying from these guys was the fact that they put it all together for me (attached all the pieces). All I had to do was hook up the water supply line and the drain line.
