Its just the collection of parts for a decent 40 inch RO system mounted on a plate. I think it goes for around the 650 mark
I have recommended many people to June at Gapswater (google Gapswater) She knows the business inside out and is brilliant to deal with. She won't sell you anything you don't need and will happily advise you as to what set up is best for you.
Tell her that I recommended you and she will charge you at least 20% more
She only uses top quality goods and will no doubt be cheaper for you.
