Anyone have experience with tti custom machine poly tanks?

[ThaBeast]

Anyone have or have had one of tti custom machine's (hotheatexchanger.com) poly water tanks? They did a heat exchanger for me since they changed hands & I was happy with it. Looking at having them make me a fresh water tank

I always wanted a waste tank from them but couldn't really justify it. When my outside filter box goes I am going to have them build me one.
