awesome deal. Less than I paid for mine, and adds a pressure gauge, tds meter, undersink drinking water tank, and faucet. Hook up on the extra filters and di resin when you buy it and it will save you a ton of money. I diddnt and still it was cheaper to order them from him. I wish I had. Its finally time to buy them again. But since its almost 100$ for the tank, faucet, and pressure gauge by them selves. I think I may just buy another unit and take advantage of the low shipping on the filters when you buy a unit, and sell my old one to someone local for 50 bucks. Steve
