Would be cheaper to make your own. That's my opinion! In my set up, I use kitty litter pans with a 1/4 inch hardware screen over a wooden frame that sits on top of the pan. I also made a v shaped indention where the food sits in and made it so a water bottle tube slips in the side of the V. This system works wonders for me. I can run 1.4 comfortably in this set up. Can do 1.6 but I find they use up water so fast, it seems every time I turn around they need water! So 1.4 is working best for me. Good luck!
