I bought a ~$1600 turn-key Savio filtration system and waterfall, pump, underlayment and liner from them. Although that is a decent amount of money, it isn't a ton; yet they were still very nice and answered all of my questions and helped me spec out the equipment. In fact, even months after I bought the stuff I emailed them and got a quick response to my questions. They also have some good YouTube videos online. My experience with them was good and so far the equipment has been working flawlessly. Hope this helps.
